Sri Chinmoy demonstrates the three steps of Samadhi: Savikalpa, Nirvikalpa and Sahaja. See unofficial transcript of text below (thanks to Adrien). August 1993. Filmed by kedarvideo, Switzerland.
“Now, I will embody and reveal and manifest what we call SAVIKALPA samadhi, this samadhi allows thought-waves to come in, but not to be affected at all. It is like the flight of birds, they are flying but the sky is not affected, the sky is not scratched. So thought may come but you are not perturbed, you are not disturbed you are not affected in any way. Your indomitable will is infinitely stronger than the thought-waves that your mind is encountering.
Now NIRVIKALPA samadhi, here there will be no thought, no iota of thought, nothing.You are in your loftiest consciousness, your aspiration-flame is up rising high, higher, highest. Nothing can prevent you from entering into your own highest transcendental consciousness and nothing will follow you. You and your own aspiring consciousness, and if you are already realized then with your realization consciousness. Nothing. You and your highest, no thought whatsoever. No incident, nothing. Absolutely you are in the world of blossoming peace, you can say blossoming peace or peace in its absolute tranquility. Here vastness and immensity and transcendental height are inseparable, and you are growing into that divinity’s reality. Nirvikalpa is infinitely higher than Savikalpa.
Now comes the third one. Believe it or not, I am telling you, even I am now playing with this (tapping the mic), most of you think that I am in my most ordinary consciousness, only my Beloved Supreme knows, whether I am in my absolute highest consciousness or not. When I cut jokes with you, when I scold you, bark at you, that consciousness I do not lose, that’s Sahaja samadhi. It becomes part and parcel of your life breath, you can’t separate your life breath from Sahaja samadhi. It is natural, more than natural, anything that you call natural in your life. It is something that not only you have but you have become, it is not only higher than the highest, it encompasses everything, the entire world, universe. The song of self transcendence. I always say that our Lord Beloved Supreme, who is my Guru, your Guru, everybody’s Guru, there is only one Guru, here on earth there in heaven, it is the Supreme.” – Sri Chinmoy
