I have clarified the metaphysics of siddhis in my book What is trading factor:
Methamatics beyond Einstein. I have explained how to gain not just eight
siddhis (Anima, Mahima, Garima, Laghima, Prapti, Prakamya, Isitva, Vasitva), but thirty-three
siddhis. If you are interested in gaining siddhi (divinity), I encourage you to read the book and
follow the directions.
Dr. Gupta traces the journey of a cell, its origins in an atom, its transformation into energy, and how energy norms the potential of divinity within each person.
