Do not go after the past,
Do not lose yourself in the future.
For the past no longer exists,
And the future is not yet here.
By looking deeply at things just as they are,
In this moment, here and now,
‘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.
