Trekchö
In Dzogchen, trekchö ("khregs chod") means "(spontaneous) cutting of tension" or "cutting through solidity." The practice of "trekchö" reflects the earliest developments of Dzogchen, with its admonition against practice. In this practice one first identifies, and then sustains recognition of, one's own innately pure, empty awareness. The main trekchö instructions in the Lamrim Yeshe Nyingpo state "This instant freshness, unspoiled by the thoughts of the three times; You directly see in actuality by letting be in naturalness." Definition. According to Malcolm Smith, "trekchö" can also be interpreted as meaning "an undone bundle", "like a hay bale with the  twine." In Vimalamitra's "Great Commentary", "trekchö" is defined as "the system of buddhahood through immediate liberation as a directly perceived realization that is not connected to appearances," and states that this is "the superior intimate instruction for the lazy who attain buddhahood instantly without meditation practice." Practice. Students receive pointing-out instruction ("sems khrid", "ngos sprod") in which a teacher introduces the student to the nature of his or her mind. According to Tsoknyi Rinpoche, these instructions are received after the preliminary practices, though there's also a tradition to give them before the preliminary practices. Tsoknyi Rinpoche states , "As for my own personal experience, when I underwent the ngondro training, I had already received some Dzogchen instructions. The awakened state of rigpa had been pointed out, and I had a lukewarm certainty about what it was. But the ngondro helped me progress. Jigme Lingpa divides the "trekchö" practice into ordinary and extraordinary instructions. The ordinary section comprises the rejection of the ""all is mind – mind is empty"" approach, which is a conceptual establishment of emptiness. Jigme Lingpa's extraordinary instructions give the instructions on the breakthrough proper, which consist of the setting out of the view ("lta ba ), the doubts and errors that may occur in practice, and some general instructions thematized as the four ways of being at leisure" ("cog bzhag"), which are "a set of brief instructions on the spheres of view ("lta ba"), meditation ("sgom pa"), activity ("spyod pa"), and result ("'bras bu")" according to van Schaik." The Seminal Heart tradition in general considers that pointing out instructions should be kept secret until the moment the lama reveals it to the student. In the "Yeshe Lama", Jigme Lingpa gives the following passage as an introduction to the nature of mind: Regarding the "four "cog bzhag"s , in the Yeshe Lama", these four ways of "freely resting" or "easily letting be" are described by Jigme Lingpa as follows: The "setting out of the view" tries to point the reader toward a direct recognition of rigpa, insisting upon the immanence of rigpa, and dismissive of meditation and effort). Insight leads to "nyamshag", "being present in the state of clarity and emptiness". To practice trekchö meditation, Jigme Lingpa states one sits cross legged with eyes open. His instructions on trekchö begin by stating that one must "settle in the present moment of gnosis ["rigpa"], without spreading out or gathering  in." Rigpa is defined as that knowledge where "the extremes of existence and nonexistence are unaccomplished."
