Our true nature is the nature of no birth and no death. We do not have to go anywhere in order to touch our true nature. The wave does not have to look for water because she is water. We do not have to look for God, we do not have to look for our ultimate dimension or nirvana, because we are nirvana, we are God.
You are what you are looking for. You are already what you want to become.
All authentic practices of the Buddha carry within themselves three essential teachings called the Dharma Seals. These three teachings of the Buddha are impermanence, no self and nirvana.
Angry in the ultimate dimension I close my eyes and look deeply. Three hundred years from now Where will you be and where shall I be?
