"Immortal Self: A Journey to the Himalayan Valley of the Amartya Masters" by Aaravindha Himadra.
"Dardura siddhi is the most practiced levitation technique and also the most accessible form, although among masters it’s rarely thought of as a genuine siddhi. The dardura technique can cause energetic surges of Shakti to burst through the body’s subtle meridians, triggering it to leap like a frog through the air but with little or no noticeable muscular involvement. Though it doesn’t fully qualify as a true levitation, it typically acts as a transitional phase in the development of the more advanced practice of laghima. However, to accomplish a full expression of laghima, a number of extenuating mental obstacles must first be overcome. Both dardura and laghima rely on identical principles. Both depend on an ability to meditatively transcend into a state of clear-light awareness. Clear-light awareness is rooted in a sustained samadhi wherein the perception-illumining power that acts as the quintessence of the psyche is no longer altered by any unconscious tendencies, patterned habits, or beliefs. Laghima requires a systematic process of constant, inwardly directed letting go while also consciously releasing one’s awareness into the resulting subtle flow of bliss. This leads to deeper and more expanded states of consciousness to where the psyche’s mental clutter no longer interferes with the inception to be weightless. Earlier in my life I had an opportunity to witness the successful performance of laghima levitation by two devout young monks living in a cloistered hermitage in northern India. Later, using what I learned, and after lengthy periods of study and practice, I personally experienced the direct potency of laghima a number of times. However, never in my life had I beheld the beauty and grace of this siddhi made so magnificent as I had this morning. It was beyond anything I imagined it could be—so free, so heavenly, so luminous and awe-inspiring."
