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. But some of these rules and discipline are good for beginners.
―Sri Ramana Maharshi
