A-sha is that mechanism , that algorithm, devised by Ahura Mazda to operate his Creation-the universe, REALITY , both at the physical and spiritual levels.
This TRUTH and Justice based belief system of the Zarathushti faith, is anchored in factual knowledge and reason. This is REALITY- the rhythm of the Universe:
A-sha, the operational mechanism of the universe, becomes the law of consequences for humanity at the spiritual level.
It is that inevitable balancing mechanism; a learning devise whereby whatever action we carry out, whether Good or Bad, comes back to us as consequences that bless (or haunt) us.
What you sow will be what you reap. It is this acquired knowledge from “experience” that enables us, to intelligently chart our future path and in effect mold our destiny.
 Arya, from Ar = energetic and ya (short for yana) = pure (divinely) intentioned.
This universal and timeless (immortal) concept of Truth and Justice, anchored in Reality is celebrated by the Ash-ao no Stoi-sh (the Stoi-स्तोइ , or Mantric Invocation to Ash-a) or the Ashem Vohu Mantra.
Yasna 27.14.: ASH-EM VOHU
Ash-em Vo-hu, Vah-ish-tem Asti,
Promoting Beloved Ash-a (Truth and Justice) with pure intent is the greatest, Real wealth;
It is that path of Light; which results in most desired (ideal) outcome
Ush-ta Ah-maai, Hyaat Ash-aai, Vah-ish-taai Ash-em
This Greatest, desired wealth (happiness), is ours (gained by us), only through acts of pure selflessness.
Knowledge after all, is the collation of facts; it is the Light, which dispatches ignorance.
This positive attitude or Positive mindedness is called Spen-ta Mun-yu.
People who cultivate positive attitudes are caring, confident and humble. They seek out the good, search for what is right in a person or situation, rather than what is wrong or apportioning of blame. Being anchored in reality, they recognize their limitations, but focus on their own strengths.
Actively seeking out the positive does not imply ignoring or overlooking faults or negative situations.
Negative attitudes or Angra Mun-yu is identified as traits such as ego, anger, malice, envy, greed and sloth. They result in bitterness, resentment, victimization complex, a pre-disposition to violence, purposeless life, high stress and its resultant poor health, to both the self as well as to others unfortunate enough to be in the same vicinity.
Yasna 28.1: Spenta-hyaa A-shaa vi-speng Shyao-th-naa
Pure, Positive, Productive intentions, are the impregnable armour for actions/deeds which are True and Just.
Knowledge, that locomotive that dispels the darkness of ignorance, or the piling up of irrefutable facts, is, therefore, considered the foundation, and Wisdom, the achieved goal based on application of the collected facts into an action plan. Truth is therefore supreme and compromise with ethics (a definition of Politics) is considered unethical.
"Aevo pan-thao yo asha-ey; Vis-pam an-y-aesham apan-tam "
There is only one logical pathway to excellence, and that is of A-SHA, All others (that undermine Knowledge or compromise with Ethics) are of no consequence and profit no one.
Symbolizing the inherent unity and inter connectivity of the universe, this knowledge based TRUTH has to be arrived at, exclusively through Love, Compassion, Humility, Patience, and Devotion. This is High Mindedness; a mentality anchored in Love.
Vohu Manah …………………………………….....2
That immortal-timeless principle representing the cords (reins) that binds, that interconnects everything in the universe.
Pictorial representation at the Surat Atar-sh Adarian of the Sun, the stars and the moon (in effect the whole universe) tied together by the cords of Vohu Manah.
This imagery is extrapolated to humanity in Yasna 44.18.:
Of achieving an expert command/control, over the 10 senses with strength and intelligence 
This bond (cord) of LOVE that supports TRUTH and Knowledge has to be applied with Power and Strength of Purpose. Love after all, conquers ALL; but knowledge (education, through collection and analysis of factual information) and the resultant dawning of wisdom, based on application of past practical experience, becomes power only when acted upon with strength of purpose. This is:
Kshathra, the Power-Strength of the Great Wise Lord/Ruler, Ahura Maz-daa. is both his Kingdom and his Power/Strength. The Great Lord Commands respect and adoration through use of Power, Wisely and with Love. Having no destructive attributes, there is no scope for demanding obedience or respect, because that is the path of the foolish tyrant. In mankind, this is the perceptive power of purpose, of commitment through knowledge (education, not instruction or indoctrination); that ability, derived from experience, to make intelligent, responsible choices (Vai-ryo) to successfully handle all of life’s situations.

Protection to successfully overcome physical (earthly) infirmities (limitations)
Yatha A-yang- haa Aada-naish Pow-ru-yo
and successful triumph over the challenges (ordeals) of life
Athra therefore represents Pure intentioned, Power-Kshathra (Will), a Force of the Great Wise Ruler, Mazda. In mankind, it is the power (commitment of purpose) fueled by wisdom and Love, to successfully handle all of life’s situations.
For Zarathushtra, devotion to the almighty is through a never ending (continuous-like a joyous ritual) positive (constructive) deeds of selflessness arrived at, intelligently, with careful and responsible deliberation and guided by the cords (reins) of love and compassion.
According to Dr Irach Taraporewalla ; this is the transformation of the worship and adoration of an abstract God head into Love of humanity. One leads by example; not duress. Devotion to Ahura Mazda, not by mere verbal declaration, but through acts of Righteousness, therefore becomes a lifestyle, and not restricted to liturgy and rituals.
Yasna 27.15.: Yenghe-hatam:
Yen-ghe haataam aat yasne paiti van-gho
Maz-da Ahu-ro vae-tha,
ash-at ha-cha, yaon-gham-cha
tan-s-cha, tao-s-cha yaza-maide.
Promoting the cause of Truth (knowledge) and Justice in unison, with the cosmic Rhythm of the Universe;
Are recognized and protected by thee, as victorious souls, O Ahura Mazda;
Each one of these, who have been and who are,
With reverence will I recall by name, And strive to emulate their example (holy deeds)
haa-taam: Vedic Satam: society, living souls
pai-ti: vedic pati: protective guide, worthy of devotion, affording protection
van-gho: victorious realm (life)
Maz-da: Great Wise Dispenser (vedic “Dha”)
Ahu-ro: Omniscient Creator
vae-tha: recognized (by),
a-sh-at: promoting Asha (Truth, Knowledge, Justice)
hach-aa: by virtue of, on the basis of
yaon-gham-cha: of such honest effort
tans-cha: of the body (tan), --- of those men and women
taos-cha: (honored family elders) of those ancestors
yaza-maide : we esteem, revere, invoke
This is the purpose behind recital of the Names of Ahura Mazda.
Ahura Mazda is the ONE, the Many, the ALL, and beyond all form.
Each attribute of Ahura Mazda, is, therefore, our divinely beloved (Vohu) Goal (Arthaa) to emulate and try to achieve.
The first rule of success, and one that supersedes all others, is to have energy. It is important to know how to concentrate it. One must focus ones’ energy on important matters instead of frittering it away on meaningless things. Nothing will add more power (ksha-tra) to ones life than concentrating all of ones’ energy on a limited set of goals.
The sun's rays do not burn until brought to a focus.
One must, therefore, gather all their resources, rally all of their faculties, marshal their energy, and focus all of their capacities on attaining the objective.
Just as the Sun is on perpetual duty, providing us with life sustaining light and heat, and ensuring the orbits of the planets around it, so too, we are enjoined to actively and energetically Espouse and aggressively promote the cause of TRUTH and JUSTICE in Life.

Procrastination is after all the sneakiest thief of every opportunity that comes ones' way. Energetic Initiative is the only logical choice; as in Life; "Change" is the only Constant.
The ability to take energetic and focused action, based on a positive and constructive plan is what separates achievers from the excuse makers.
Thu-voi aas ara-mai-tish ; Thu-vey aa geush taa-shaa aas khra-tush
Thou art our guide, O Aramaiti, embodying the earth, clarifying our goals, igniting in us, motivation for the cause of Truth and Justice.
It is only through ones’ own conscience that a man ascertains what is right from what is wrong. The conscience therefore perforce has to be intelligently developed and strengthened. For like a color blind man unable to distinguish between colors, the man of perverted conscience cannot distinguish between right and wrong.
Mastering the conscience and the above mentioned faculties requires INSPIRATION. This is SRA-OSH, the divine Light (osh/Ush) that Inspires/Stimulates (Sr ) the mental faculties. This is the fifth immortal and sovereign principle.
Sra-osh (Divine Inspiration)...................5:
Listen actively and attentively to Sra-osh; extract that wealth, that divine inspirational advice to the highest Good.
Derived from the root “Sr”, meaning to hear, to be mentally stimulated, and “osh”, meaning divine Light; “Sra-osh” means Divine Inspiration. This divinely inspired guidance infuses in devotees a sense of Direction when tossed about in doubt.
The Gathas , the bedrock of Zarathushti philosophy, composed by our Saviour (Pai-gam-ber ); Zarathushtra, are thus called “Sraa-vee”, (just as the Vedas are called, Shru-ti), a word, meaning "divinely revealed/inspired Scripture".
Both are derived from the root word “Sr”. Being Mantras, they have a rhythmic meter , with a specific sound syllable and resulting vibration , inspiring the devotee to a higher purpose.
Mantra literally means 'instrument of thought'; that which when intoned stimulates the mind. They are devotional mantric hymns, which through their intrinsic quality of stimulation of the intellect and reasoning faculties, benefit those who chant them with devotion and understanding. They form the original constituents of the Gathas.
This 5 Fold Path (Pancha Tak-aesha) are thus the Eternal Positive (Amesha Spenta) and Timeless-Immortal principles (concepts) to be followed with a positive (Spenta) attitude (Mun-yu) to successfully achieve the goal of Perfection or self realization (Ha-urva-tat) and subsequent Immortality through merger in Divinity (Amere-tat).
Yasna 31.6:The mantra of Ha-urva-tat (Perfection-Self Realization):
Stimulate my intellect with the best, That mantra of Ha-urva-tat :That prosperity, that perfect state of self realization, achieved through knowledge and doubtless comprehension.
