After some time in meditation I find that thought dies away and stillness reigns. Within that stillness, I am aware of a tiny seed or point in my breast or heart upon which all my attention is centered. Is this the Self you mention?
M: Yes, that is the Self, though you have to go deeper to perfect your realization. Hold onto it. Do not lose the current. Do not lose it by having the wrong idea that 'I am meditating on the Self,' or 'I am meditating on something else.'
At such a point try to remember that you ARE the Self, that this stillness is your natural condition. Watch vigilantly that you do not wander away from it.
