Heroism, power, determination, ingenuity, courage in battle, generosity, and the art of ruling are the qualities that accompany the act of the ksatriya [warrior and administrator].

Ability to cultivate the land, to care for cattle and to trade, these are related to the act of the vaisya [merchant and farmer]. As for the sudra [worker], it is his nature to serve others by his work.

Through his actions and his own nature, every man can know perfection.

By following his own nature in his actions, every man can know perfection. How to accomplish this, hear Me tell you now.

By worshipping the Lord, the Omnipresent, the origin of all beings, man can, in the performance of his own duty, attain perfection.

It is better to perform one's own duty, even if imperfectly, than to take on the duty of another, even to perform it perfectly. By fulfilling the prescribed duties, which one's nature assigns to each, one never incurs sin.

As fire is covered by smoke, so every undertaking is veiled by some fault. Therefore, no one should abandon the act proper to his nature, even if it be stained.

Man can taste the fruits of renunciation through simple self-control, detachment from worldly things and disinterest in material pleasures. Herein lies the highest perfection of renunciation.

This is how to attain the supreme perfection, the spiritual level.

Briefly, learn from Me how, if one acts in the way I am going to explain to you, one can attain the supreme perfection, the level of the brahman [spiritual being].

Entirely purified by intelligence, mastering the mind with determination, renouncing the objects that give pleasure to the senses, free from attachment and aversion, the man who lives in a secluded place, who eats little and controls the body and the tongue, who always remains in contemplation, detached, without false ego, without vain power or vain glory, without lust or anger, who closes himself to material things, free from all feeling of possession, serene, this man is raised to the level of spiritual realization.

The one who attains the spiritual level at the same time realizes the Supreme Brahman [the Supreme Being], and finds infinite joy in it. He never grieves, never aspires for anything; he is equal to all beings. He then gets to serve Me with pure love and devotion.
