The Bhagavad Gita · 4 of 4 · tr. Kashinath Trimbak Telang
Chapter XVIII, Section 1d
This you should never declare to one who performs no penance , who is not a devotee , nor to one who does not wait on (some preceptor) , nor yet to one who calumniates me.
He who, with the highest devotion to me, will proclaim this supreme mystery among my devotees, will come to me, freed from (all) doubt.
No one amongst men is superior to him in doing what is dear to me.
And there will never be another on earth dearer to me than he.
And he who will study this holy dialogue of ours, will, such is my opinion, have offered to me the sacrifice of knowledge .
And the man, also, who with faith and without carping will listen (to this), will be freed (from sin), and attain to the holy regions of those who perform pious acts .
Have you listened to this, O son of P ri thâ!
with a mind (fixed) on (this) one point only?
Has your delusion (caused) by ignorance been destroyed, O Dhanañ g aya?
Ar g una said: Destroyed is my delusion; by your favour, O undegraded one!
I (now) recollect myself.
I stand freed from doubts .
I will do your bidding.
Sañ g aya said: Thus did I hear this dialogue between Vâsudeva and the high-minded son of P ri thâ, (a dialogue) wonderful and causing the hair to stand on end.
By the favour of Vyâsa, I heard this highest mystery, (this) devotion , from K ri sh n a himself, the lord of the possessors of mystic power, who proclaimed it in person.
O king!
remembering and (again) remembering this wonderful and holy dialogue of Ke s ava and Ar g una, I rejoice over and over again.
And remembering and (again) remembering that excessively wonderful form of Hari also, great is my amazement, O king!
and I rejoice over and over again.
Wherever (is) K ri sh n a, the lord of the possessors of mystic power, wherever (is the (great) archer, the son of Prithâ, there in my opinion (are) fortune, victory, prosperity , and eternal justice.
Esoteric teachings reserved for those ready to receive them; outer meaning conceals an inner liberating truth.
The passage explicitly restricts the 'supreme mystery' to those who perform penance, are devotees, and serve a preceptor, while forbidding its declaration to others.
