The Vedic culture of India is steeped in esoteric knowledge, and has developed to such a degree that the sages in this culture have discovered the soul. They have also discovered God within and without, and through research into the Supreme Personality of Godhead, they have even discovered and realised different relationships with God. We can never imagine or realise transcendental relationships with the Supreme Personality of Godhead through our imperfect material senses and knowledge. However, the Supreme Lord Sri Krishna Himself transmits transcendental knowledge through an unbroken succession of spiritual masters and disciples and the true nature of devotion in this book describes those pastimes.
