All bad qualities centre round the ego. When the ego is gone, Realisation results by itself. There are neither good nor bad qualities in the Self. The Self is free from all qualities. Qualities pertain to the mind only.
If there is anything besides the Self there is reason to fear? Who sees the second? First, the ego arises and sees objects as external. If the ego does not rise, the Self alone exists and there is no second.
Time is only an idea. There is only the Reality. Whatever you think it is, it looks like that. If you call it time, it is time. If you call it existence, it is existence, and so on. After calling it time, you divide it into days and nights, months, years, hours, minutes, etc. Time is immaterial for the Path of Knowledge.
Concentration of the mind is in a way common to both Knowledge and Yoga. Yoga aims at union of the individual with the universal, the Reality. This Reality cannot be new. It must exist even now, and it does exist.
It is the Higher Power which does everything, and the man is only a tool. If he accepts that position, he is free from troubles; otherwise, he courts them.
Even the structure of the atom has been found by the mind. Therefore the mind is subtler than the atom. That which is behind the mind, namely the individual soul, is subtler than the mind.
