Whatever the mind does is very noticeable, because there is a lot of friction and a lot of noise contained in it.
When the mind does something it is always with a lot of noise, and fanfare, and show, and demonstration.
When it happens from the True Self, it happens with a great felicity, with a great ease.
It is smooth. You cannot notice it.
It is almost a non-happening.
That is ‘sahajtaa’.
