See the beautiful translation of Sir Edwin Arnold
Lord Krishna tells Arjuna
Now again will I open unto thee
This Secret of all screts, that which possessing
All my Sages have passed
To perfectnes;
That farthest secret of my Heavens and Earths
A royal lore, a kingly mystery
Easy to walk by, inexhaustible !
Param bhooya pravakshyami
Jnanam Jnanam uthaman
Yajnathva munaya sarve
Param siddhi mitho gatah !
– The Song Celestial, translation of the Geetha
