Samagana is said to be the most mellifluous harmony of sound. Since Sama originates from prana we must use it with utmost care. The Yajur Veda is repository of spiritual formulae and is an embodiment of effulgence. Describing the Lord as the very embodiment of light, it seeks to experience the Light. The Rig Veda is the repository of light. The Yajur Veda is the repository of rituals and Sama Veda is the embodiment of sound. These three Vedas are essential for world peace. The Vedas inspire us to chant the glory the Lord with mantras and delight Him with music. The three Vedas descended on the world to enable man to merge into the Lord by listening and singing His glory. Songs are more powerful than words and verses. You cannot melt the heart of the Lord by mere speech. Whereas speech is dull, singing is highly inspiring. Songs have the superlative capacity of merging the individual soul into the Absolute Soul. The Nyaya philosophy is a sublime philosophy that dispels doubts and regales the human heart.
There is no greater Veda Sadhana than the Sadhana of understanding the six systems of philosophy. The study of the six systems delights our hearts, reveals the mysteries of the universe and imparts the supreme knowledge to us. Ignorant of the sublime Indian literature, the students of today lead wayward lives. The Shaddarshanas contain in themselves the very essence of the scriptures, which the sages distilled by profound investigation and enquiry. (SSB 1993, p. 87)
