One approach to translating Tilopa’s Six Words is for to capture the laconic cadence of the Tibetan::

Don't recall.
Don't imagine.
Don't think.
Don't examine.
Don't control.
Rest.

Another approach is to bring out the meaning of each instruction, as in this translation.

Let go of what has passed.
Let go of what may come.
Let go of what is happening now.
Don't try to figure anything out.
Don't try to make anything happen.
Relax, right now, and rest.

During the three-year retreats (1976 – 1983), I translated The Six Words many times. Of all the translations I did, the two presented here have appealed to the most people and have been the most widely circulated. Some time around 2010 I came to conclusion that further versions were not needed and have let these two stand.
