In accordance with Yathartha Geeta, as soon as you begin to study the teachings of the Geeta, the God would guide you to the right Guru. You will be guided from within. Your doubts would be dissolved. You will be awakened from within and would gradually proceed on the path of divinity.
There is only one Geeta in this universe. Where are different Geeta? More than five thousand years ago the civilization was smouldering in the violent inferno of hatred. Large armies of Kauravas and Pandavas stood facing each other for war. Amidst them Lord Krishna sermonised the Geeta, but there were only two listeners. One was Arjun, while other listener was Sanjay who was listening from afar.
