" I have two of these spiritual gurus (Swami Vivekananda and Sri Aurobindo) whom I did not meet. I also had two living gurus in Jawaharlal Nehru for politics and Dr Radhakrishnan for philosophy. In my spiritual quest, I have had a whole spectrum of spiritual gurus; a Shakta guru who was a Kashmiri pandit, a Vaishnava guru who was an Englishman, a Shaiva guru who was an American, a Sufi guru who was Muslim, a Kriya yoga guru who is from Kerala. So, I have been blessed with a number of gurus and teachings around the world. "
