I found 2 more versions of this song, and there are some interesting differences among them.

LEELA LEELA
(©1974 Tantra Research Institute arr. Marley's Ghost)

CHO: Leela, Leela, this life is just a game.
Winners lose and losers win. The game is still the same.
Leela, Leela, this world is just a play.
Those who say don't know and those who know don't say.

The eyes of the baby look at everything from under.
The eyes of the young man behold his lady's face with wonder.
The eyes of the old man look upon the flowing river.
What of those whose eyes are one? They leave the world forever. CHO.

And where is the man who in his heart can really feel it?
Can he feel it in himself, and then can he reveal it?
Then let him sit and sing and sail the flowing river.
Snakes and arrows cannot go where sound remains forever. CHO.

How can a man accept life who has not accepted dying?
How can he achieve his purpose without even trying?
How can a man have courage who cannot as well be tender?
He who wins the game is he who's learning to surrender. CHO.

And show me the man who in his heart can really feel it.
Can he feel it in himself, and then can he reveal it?
Then let him sit and sing and let his heart grow gladder.
Chant to God until the masquerade no longer matters. CHO.

Those who say don't know and those who know don't say.

[Recorded by Marley's Ghost on "Across the River," 1998.]
