The knower, the knowledge and the process of knowing are not different things; they are one. Removing the non-self is the only way to know the Self. Real practice is to establish oneself in the Self Atma) forgetting the non-self (anatman). Without this conviction, all practices are just mental illusions. Like the clouds created by the heat of the sun, hiding the sun, the mind that arises out of the self hides the Self. (L&L, p. 5)

The Self (atman) is Bliss. It is Beauty and Wisdom, but we allow it to be tarnished by the ego. Engage in humble service and egotism will fade away. (SSS Vol.14)

The vehicle of human life is drawn on two wheels, by the Senses which are driven by Buddhi (intellect), with Viveka and Vairagya (discrimination and detachment) as the reins, the two wheels being the Kala Chakra and Karma Chakra (the wheels of Time and Action). The spokes of the wheel are the rules of Dharma, bound by the rim of Prema. The Self is the rider and he will not come to harm if the axle is Satya and the goal is Shanti. (SSS Vol.2, p. 40)

Absence of self-confidence is the cause of all miseries and troubles man encounters in the world. One should have confidence in his own inner Self that is the Atma. If one has this self-confidence, he will have self-satisfaction, which will lead to self-sacrifice. Self-sacrifice leads to liberation or Self-Realisation. Everything is based on "Self" and everyone is Atma swarupa (embodiment of the Self). The body is just an instrument. There is water in the tumbler. Without the tumbler water can t be kept; the tumbler is the basis for the water which is needed to quench the thirst. So also, the body is the vessel to hold the water of Divinity. To drink the water is Sadhana. Your thirst for realising Divinity is quenched by Sadhana. (SSS Vol.26)
