In every seeker’s life there comes a time when the heart is at unease, and there is restlessness. In the West, it is known as the “dark day of the soul”. There comes a time when satvik shakti (positive energy) is less and rajoguna and tamoguna are high, that leads to the restlessness.
There are three kinds of taap (penance) and one such taap is known as adhyatmic taap (spiritual misery). Yet it is for a short while. Therefore satsang is very important, especially when you don’t feel like doing it.
Once in twelve years a lack in spirituality comes up. There will arise a doubt on the self, the path and the Guru. This is what the scriptures say. Therefore the Kumbh festival takes place once in twelve years and all the saints get together to clear all their sins. This tradition is very old. A place where seekers do satsang and where Vedas are recited- kaliyug never comes there.
