Perseverance is the essential requirement in the practice of yoga. It has to be done day by day, week by week, year by year, until the mind is brought to the 'still point' where it is open to the grace of God.

This process of change since my stroke has been very gradual. It is going on all the time... It is partly a physical transformation. The body itself is undergoing great changes. My problem before was that I was living largely from the head; and then after the stroke I got down into the heart.

I was being called to surrender the very citadel of my self. I was completely in the dark. I did not really know what repentance was or what I was required to repent of. It was indeed the turning point of my life.

There is a beautiful expression of this in the Chandogya Upanishad: 'There is this City of Brahman, (that is the body), and in this city there is a shrine, and in that shrine there is a small lotus, and in that lotus there is a small space, (akasa). Now what exists within that small space, that is to be sought, that is to be understood.' This is the great discovery of the Upanishads, this inner shrine, this guha, or cave of the heart, where the inner meaning of life, of all human existence, is to be found.
