Fine delle trasmissioni

Before his death, Garab Dorje imparted his last testament
to Manjushrimitra.

These three precepts, known as the
Three Words that Strike to the Heart of the Essential Point

or Tsig Sum Nèdek
(Tibetan: tshig gSum gNad brDeg) 

summarize the whole of the Dzogchen teachings:

One is introduced directly to one’s true nature
or “Direct introduction.” 
One attains certainty about this natural state
or “Remaining without doubt.” 
One continues with confidence in liberation
or “Continuing in the non-dual state.”
