The following excerpt was taken from The Summits of God-Life: Samadhi and Siddhi by Sri Chinmoy.
Sahaja samadhi encompasses the other samadhis – savikalpa and nirvikalpa – and it goes beyond, beyond. Samadhi is like a big building with many floors. When one is in sahaja samadhi, he is the owner of the whole building. He has the height of nirvikalpa, and the heights far above that, and at the same time he has achieved the perfection, wealth and capacity of all the other floors. On the one hand he has encompassed within himself all the Doors, and on the other hand he is above them. Nirvikalpa is like one height, say the thirtieth floor; it is very high, but it has only its own limited capacity. It cannot bring any of its capacity to the basement. If one has nirvikalpa, he is afraid to go down into the basement, because he may not be able to go back up again. But sahaja consciousness is above the thirtieth floor and, at the same time, it can be in the basement also. Sahaja samadhi will not be satisfied with thirtieth floor; it will be satisfied only when it touches the basement, the first floor, the second floor, all the floors. The power of sahaja samadhi is such that it can take one to any floor.
