Bhagavadgita is the best thing that has happened to humanity. While the other religious books seperate people into different sections and teach you that salvation is gauranteed to you if you follow a particular path and whoever does not believe in it go to hell, Bhagavadgita addresses humanity and there are no conditions and compulsions.
Bhagavadgita is more scientific than religious. This is not confined to a religion. Despite the best efforts of Edvin Arnold, it is impossible to carry the same beauty of Gita into English translation as it is in the original, but i must congratulate Mr. Arnold for it appears to be the best translation of Gita in English.
