Sutra I. 48 Rtambhara tatra prajna

Commentary: Here the inner truth, knowledge, or Gnosis (prajna) which bears the truth within itself (rtambhara) shines forth on its own unimpeded, hence self-arisen and innate. This is a pivotal statement of the most sublime goal of Yoga according to Patanjali. It should be noted that Patanjali once again states that this wisdom is intrinsic and innate, but was simply obscured (by the citta-vrtti). It is innate, unconditioned, and natural, not needing cultivation or contrivation but simply the elimination of the citta-vrtti . Thus yoga works on the pre-existing contrived and conditioned mental processes (the vrtti) and eliminates them (by eventually eliminating all samskara) so that the practitioner abides in their natural true Self (swarupa).

As will be explained later rtam-bhara prajna is none other than the absorption and complete integration of the dharma-megha (the rain cloud of dharma), which is none other than the absorption of Sanatana Dharma (the unification with the stream of eternal truth or realm of dharmakaya). See: IV 29-30.

Christopher Chapple and Yogi Ananda in "The Yoga Sutras of Patanjali" (Sri Satguru Publications, Delhi, 1990) translate this as: "This wisdom sustains the movement of life. Ignorance is to fall from this [intrinsic] order."

As such it is the primordial innate timeless motif, the bodhi-citta, the param-purusa, or primordial and timeless wisdom seed, which has no prior seed. It is self-arising To summarize, nirvicara samadhi leads toward nirbija samadhi, but still is not capable by itself of destroying the seeds which cause the falling out of this intimate unitive state (samadhi) which is the realization/embodiment of our innate wisdom potential (the inner Buddha, Christ, Sat Guru, or Brahman) in the form of the jivamuktan. To remove this seed (caused by past samskaras), Patanjali next addresses the removal of samskaras.
