Bhagavad Gita 18.40न तदस्ति पृथिव्यां वा दिवि देवेषु वा पुनः।सत्त्वं प्रकृतिजैर्मुक्तं यदेभिः स्यात्ित्रभिर्गुणैः ॥

The Gunas form the warp and woof of everything as threads do in the case of cloth.Here in the world of mortals or there in the heavenworld, there is no creature that is not bound by the three alities of Nature. Can there be a cloth without threads Can there be a man without blood and bones Can there be a mountain without stones Even so there is not a single creature in the whole universe into whose composition the three alities of matter do not enter. The whole of creation is wrought of these three alities. They have given rise to the Trinity (Brahma, Vishnu and Siva). In the world of mortals the triplicity of agent, action and fruit owe their origin to them. They are the cause of the different functions of the four castes. This Samsara has been compared to the peepul tree in chapter XV.1. This Samsara is made up of the three alities and is kept up by the force of ignorance.Action, instruments of action and fruits have set the wheel of Samsara in motion and this wheel is revolving from beginningless time. It is only a liberated sage who has attained knowledge of the Self who puts a check to this wheel, goes beyond the cause and the effect, and breaks the bonds of Karma.Cut this mysterious tree of Samsara with the strong sword of nonattachment, transcend the three Gunas and rest in your own essential divine nature as ExistenceKnowledgeBliss Absolute.
