A practitioner who has attained the state of rigpa and is able to rest in it continuously is called a Rigdzin or Rigma (see Vidyadhara), which may be used as a title either pre- or post-nominally.
[14] Sam van Schaik translates rigpa as "gnosis" which he glosses as "a form of awareness aligned to the nirvanic state, free from all delusion".
[15] He notes that other definitions of rigpa include "free from elaborations" (srpos bral), "non conceptual" (rtog med) and "transcendent of the intellect" (blo 'das).
[15] The unconditioned nature of rigpa is described in the Longchen Nyingthig as follows: Not constructed by excellent buddhas, nor changed by lowly sentient beings, this unfabricated gnosis of the present moment, is the reflexive luminosity, naked and stainless, the Primordial Lord himself.
[16]John W. Pettit notes that rigpa is seen as beyond affirmation and negation, acceptance and rejection, and therefore it is known as "natural" (ma bcos pa) and "effortless" (rtsol med) once recognized.
[3] Vimalamitra's Commentary states that "because the aim of buddhahood exists in the manner of a seed in the pristine consciousness of one’s vidyā, there is definitely success through practice.
The Realms and Transformations of Sound Tantra states: "The jewel present within the heart in the center of one’s body is great pristine consciousness.
[22] Dzogchen tantras also discuss the related topic of the energy body, mainly the nāḍīs, vāyus, and bindus (rtsa, rlung, and thig le; channels, winds and circles).
[22] According to Van Schaik, there is a certain tension in Dzogchen thought (as in other forms of Buddhism) between the idea that samsara and nirvana are immanent within each other and yet are still different.
[23] In the Longdé texts (and in other works), a common term used to denote the immanent enlightened nature is bodhicitta (byang chub sems).
[16] This lack of difference between these two states, their non-dual (advaya) nature, corresponds with the idea that change from one to another doesn't happen due to an ordinary process of causation but is an instantaneous and perfect 'self-recognition' (rang ngo sprod) of what is already innately (lhan-skyes) there.
[24] According to John W. Pettit, this idea has its roots in Indian texts such as Nagarjuna's Mulamadhyamakakarika, which states that samsara and nirvana are not separate and that there is no difference between the "doer", the "going" and the "going to" (i.e. the ground, path and fruit).
[27] According to the 14th Dalai Lama, "sems is the mind which is temporarily obscured and distorted by thoughts based upon the dualistic perceptions of subject and object.
[citation needed] Citing Dodrupchen Jikme Tenpe Nyima, the 14th Dalai Lama states the full measure of rigpa occurs with the third vision.
An important theme in Dzogchen texts is explaining how ignorance arises from the basis or Dharmata, which is associated with ye shes or pristine consciousness.
That so-called “knower” (rig pa po) or “mind” (the special assertion of a consciousness demonstrated in our own texts) is deluded.
[24] However, some beings do not lapse into dualism by externalizing their own display and instead immediately recognize all phenomena which arise from the basis as the insubstantial appearances of their own nature.
[37]As Sam van Schaik notes, for authors like Longchenpa and Jigme Lingpa, the basis has the potential to manifest in both a samsaric and a nirvanic modes.
Mind is the aspect of deceptive objects of fixation, vividly filling up, swirling round, and pouring out again, or briefly becoming agitated like a hurricane.
Thus the essential point of the Seminal Heart is to hold a secure place in the natural state, utterly liberated from mind in the expanse of gnosis.
[42]Longchenpa explains the difference thus: In brief, ‘‘mind and mental factors’’ refer to the arising of conceptualization and analysis of objects that is ostensibly causally produced by the subject-object dichotomy.
[48] According to Thrangu Rinpoche, Rangjung Dorje (1284–1339), the third Karmapa Lama (head of the Karma Kagyu) and Nyingma lineage holder, also stated that the Ground is Buddha-nature.
