The Book of the Religion of Knowledge

Krishna.
This deathless Yoga, this deep union,
I taught Vivaswata,[6] the Lord of Light;
Vivaswata to Manu gave it; he
To Ikshwaku; so passed it down the line
Of all my royal Rishis. Then, with years,
The truth grew dim and perished, noble Prince!
Now once again to thee it is declared--
This ancient lore, this mystery supreme--
Seeing I find thee votary and friend.

Arjuna.
Thy birth, dear Lord, was in these later days,
And bright Vivaswata's preceded time!
How shall I comprehend this thing thou sayest,
"From the beginning it was I who taught?"

Krishna.
Manifold the renewals of my birth
Have been, Arjuna! and of thy births, too!
But mine I know, and thine thou knowest not,
O Slayer of thy Foes! Albeit I be
Unborn, undying, indestructible,
The Lord of all things living; not the less--
By Maya, by my magic which I stamp
On floating Nature-forms, the primal vast--
I come, and go, and come. When Righteousness
Declines, O Bharata! when Wickedness
Is strong, I rise, from age to age, and take
Visible shape, and move a man with men,
Succouring the good, thrusting the evil back,
And setting Virtue on her seat again.
Who knows the truth touching my births on earth
And my divine work, when he quits the flesh
Puts on its load no more, falls no more down
To earthly birth: to Me he comes, dear Prince!
Many there be who come! from fear set free,
From anger, from desire; keeping their hearts
Fixed upon me--my Faithful--purified
By sacred flame of Knowledge. Such as these
Mix with my being. Whoso worship me,
Them I exalt; but all men everywhere
Shall fall into my path; albeit, those souls
Which seek reward for works, make sacrifice
Now, to the lower gods. I say to thee
Here have they their reward. But I am He
Made the Four Castes, and portioned them a place
After their qualities and gifts. Yea, I
Created, the Reposeful; I that live
Immortally, made all those mortal births:
For works soil not my essence, being works
Wrought uninvolved.[7] Who knows me acting thus
Unchained by action, action binds not him;
And, so perceiving, all those saints of old
Worked, seeking for deliverance. Work thou
As, in the days gone by, thy fathers did.

Thou sayst, perplexed, It hath been asked before
By singers and by sages, "What is act,
And what inaction? "I will teach thee this,
And, knowing, thou shalt learn which work doth save
Needs must one rightly meditate those three--
Doing,--not doing,--and undoing. Here
Thorny and dark the path is! He who sees
How action may be rest, rest action--he
Is wisest 'mid his kind; he hath the truth!
He doeth well, acting or resting. Freed
