'All actions are wrought by the qualities of nature only. The self, deluded by egoism, thinketh, 'I am the doer.' but he, who knoweth the essence of the divisions of the qualities and functions, holding that 'the qualities' move amid the qualities, is not attached. 'By meditating upon these two shlokas, you can separate yourself from the three gunas - qualities of nature. 'He who seeth that prakriti (nature) verily performeth all actions, and that the self is actionless, he seeth.' (Chapter XIII – Verse 2).
The salt of life is selfless service. The bread of life is all-embracing love. The water of life is purity.
