To battle against the tendency of body identification and to win the grace of God, spiritual exercises such as philosophical inquiry (Tatwa Vicharana), mind and sense control (sama-dama) and other six-fold spiritual disciplines (shat-sampatti) have been laid down. Their practice will ensure the purification of the consciousness; it will then become like a clean mirror that can reflect any object, and the Atma will stand revealed clearly. For the attainment of the highest wisdom (jnana-siddhi), cleansing of the consciousness (chitta-suddhi) is the royal path. For the pure in heart, this is easy to achieve. This is the central truth of the Bharatiya search for the ultimate reality (Paramartha). This is the very vital breath of the teaching. (Sathya Sai Vahini, Ch 1)
