"SANATHANA DHARMA, which  connotes the way of life for all humanity,  is based on the VEDAS which furnish guidelines on all subjects necessary for the well being of humanity and is applicable to all times. Vedic Chanting, according to the prescribed rules, leads not only to collective prosperity and individual well being, but also avoids natural calamities and mitigates evils . Invocation of Devatas and their blessings, leads to universal prosperity, ushering peace and contentment everywhere.  Utilisation of the Vedic mantras in the samskaras (Rituals) helps the spiritual growth of the individual, purifies the atmosphere and helps curtail illness and other evil effects.

This vast storehouse of knowledge and ancient wisdom in ALL the Disciplines -- you name any and you can trace it to the Vedas -- was codified by Bhagvan Sri Veda Vyasa into the four Rig, Yajur, Sama and Atharva Vedas and further split into 1131 Sakhas (Rescensions) in the beginning of time. 

Until recently, they have been handed down from generation to generation by oral teaching in the Gurukula, Guru-Sishya tradition without any written text. Its pristine purity in terms of Pronunciation, Swara (intonation), and etymology had been preserved in a unique time tested form, down the millennia."
