I would like to thank my father, my brothers Manoj Agrawal and Sumit Mund for their mentorship. Without learning from them, there is not a chance I could be doing what I do today, and it is because of them and others that I feel compelled to pass my knowledge on to those willing to learn. Special thanks to my mentor and coauthor Srinivas Duvvuri, and my friend Priyansu Panda, without their efforts this book quite possibly would not have happened.

My deepest gratitude to his holiness Sri Sri Ravi Shankar for building me to what I am today. Many thanks and gratitude to my parents and my wife Yashoda for their unconditional love and support.
