Know Thyself: Jnana Yoga - Part 2 by Omraam Mikhaël Aïvanhov

'«Know thyself»! All science and all wisdom lies in knowing oneself, in finding oneself, in the fusion of one's lower self with one's higher self. The symbol of the initiate who has succeeded in finding himself is the serpent with its tail in its mouth. A serpent forms a straight or wavy line, and a line is limited. But the serpent with its tail in its mouth forms a cirde and a cirde represents the infinite, the limitless, the eternal. He who succeeds in becoming a circle enters a world without limitations where the 'above' and the 'below' are no longer separated, because all the powers and all the riches and virtues of the true, higher self have been infused into the lower self. The higher and the lower become one and man becomes a divinity.'
