To establish oneself firmly in a successful life on this planet, a certain education, commitment, discipline and wisdom is needed, nay highly recommended.
To aid in one's study and to help in being sincere and focused, the OUTSTANDING ancient texts and body of knowledge have been broadly segregated as:
SONG = GITA
THOUGHT = SUTRA
SPELL = MANTRA
This book gives a lucid commentary on the aforementioned texts, using these as a valid example for Gita Sutra Mantra; and using words and terms that are commonly used and easily understood in the present age.
