I have never said that there is no need for a guru. All depends on what you call guru. He need not be in a human form.

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.

Actions yield result by the ordinance of God as He wills.

If you are vigilant and make a stern effort to reject every thought when it rises, you will soon find that you are going deeper and deeper into your own inner self, where there is no need for your effort to reject the thoughts.

That which comes and goes, rises and sets, is born and dies is the ego. That which always abides, never changes, and is devoid of qualities is the Self.

Doubts never end. If one doubt is removed, another takes its place. It is like removing the leaves of a tree one by one. Even if all the leaves are clipped off, new ones grow. The tree itself must be uprooted.
