The delusional secular mind and the true mind* are like the two sides of the same coin.
Just like the wave that rises and the wave that falls, they are both part of the same ocean.
*true mind, or also known as the original nature or real self in some other contexts, is an opposing terminology to the false identification of the deluded secular mind. It is unfathomable by the secular mind and should never be conceived as an 'object'.
