That which you seek to know you can definitely know.
O dear ones endeavor to know the atman – the self, it is not enough if you are merely convinced that you are the Self. Without the elimination of the latent tendencies, vasanas, the spiritual state cannot be fixed upon. In the unstable substance of the mind, peace definitely cannot stay.
When the mind is restrained, humility and patience will begin know this for sure.
It is not easy to conquer the mind, endeavor tirelessly, definitely it becomes possible.
