The Bhagavad Gita. The Srimad-Bhagavad-Gita, the Essence of the Upanishads, the Science of Brahman, the Scripture of Yoga, the Dialogue between Sri Krishna and Arjuna.
This book contains the complete text of the Srimad-Bhagavad-Gita as translated by Swami Paramananda. There are numerous other translations available. This is the basic text only. There is also a short discussion of the historical background on the next card (card 2). The Bhagavad Gita was originally a part of much larger Mahabharata, an introduction to which is on card 3. Future editions will be accompanied by more commentaries and background, more links to other Indian works and, eventually, the Sanskrit text.
