When you are born you cry,
but the whole world is overjoyed.
When you die the whole world cries,
but you may find the great liberation.
Quote from Bardo Thodol
It is the single (nature of) mind which encompasses all of Samsara and Nirvana.
Even though its inherent nature has existed from the very beginning, you have not recognized it;
Even though its clarity and presence has been uninterrupted, you have not yet encountered its face.
Even though its arising has nowhere been obstructed, still you have not comprehended it.
Therefore, this (direct introduction) is for the purpose of bringing you to self-recognition.
Everything that is expounded by the Victorious Ones of the three times
In the eighty-four thousand Gateways to the Dharma.
Is incomprehensible (unless you understand intrinsic awareness).
Indeed, the Victorious Ones do not teach anything other than the understanding of this.
Since things neither exist nor don't exist,
are neither real nor unreal,
are utterly beyond adopting and rejecting -
one might as well burst out laughing.
