Hi Vinayak,
I would suggest the following:
1) "Many Lives, Many Masters" by Brian L. Weiss
2) "Awakening the Giant Within" by Tony Robbins (Also available in an audio version)
3) "The Power of Now" by Eckhart Tolle
4) "The Fountainhead" (Fictional) by Ayn Rand
5) "Rich Dad, Poor Dad" (Also available in an audio version)
Regards,
Kenneth
