each one of us has an infinite source of creative power mostly dormant. For some like Ramanujan, it's awakened with a greater degree. The book goes into steps to awaken it and I can attest to it that with quality meditation and perseverance, this can be gradually awakened and channelized. A sincere practitioner starts to get experiences (verifying he's onto something) within a month of regular, quality practice.
This can be awakened by meditation, devotion (like in case of Ramanujan) or by selfless work. All of them falls under Yoga, which means "to unite" with your true self, the infinitely powerful, whose nature is self-existence, knowledge and bliss.
