Nirvana...

By going beyond the level of being able to meditate in deep sleep, you will reach a place of perfect serenity, your original, bright, shining mirror devoid of all dust that had sat on it. You will see your original face, your true nature, the nature of the entire universe, and realize that you had always and originally been a Buddha. This is nirvana.

Many practitioners believe that they have attained enlightenment. Some say they have attained it multiple times. This is a big delusion. There is only one true enlightenment, such that the attained state never disappears and then reappears, but is constantly present even through the deepest sleep.



Tong Songchol (1912~1993), one of the great Zen masters of Korea in the last century, was called the 'Living Buddha of Korea'
