WHETHER VEDA MANTRAS CAN BE SET TO MUSIC AND SUNG?

Vedic Mantra Chanting has to be done orally only by competent persons who have undergone the studies from the Vedacharyas. According to tradition, the Veda mantras have to be duly chanted in line with the Varna and Svara . Thus Akshara suddhi (proper pronunciation of letters), Svara suddhi (proper usage of Svaras) along with proper Matra (metrical unit of time) are required. The Vedic heritage has to be duly protected and nourished. Improper rendition of the Veda Mantras reduces the life span and leads to diesease. Hence it is important to preserve the integrity and authenticity of the Veda Mantras passed on from the ancient great Rishis.

गीती शीघ्री शिरःकम्पी तथा लिखित पाठकः।
अनर्थज्ञः अल्पकण्ठश्च षडेते पाठकाधमाः ॥
