Shri Mataji on Gyaneshwara on his 700th Birth Anniversary (Pune, 1996):
"Today I am going to tell you, we have within us all these powers. As Shri Gyaneshwara had described in the sixth chapter, that there is a force called Kundalini within us which when awakened gives you the self. But as you know everywhere, there are fundamentalist, we call them dharma martanda. And they said that “This is something that one should just avoid, this we cannot.” Because they can't do it. So that was not read anymore. Neither people ever tried to have.
But in these modern times, it is predicted that is going to happen to thousands of people... A specialty of this age, that it is happening all over the world. I am surprised Myself. This is the power that you have within yourself. I am not obliged. Neither you are obliged. It is your own power that rises and gives you this self-hood which is being described by Shri Sant Gyaneshwara. And this state of Sahajavastha is very easy to achieve."
