Sutra 29 tatah pratyak-cetanadhigamo'py antarayabhavash ca

Commentary: By  surrendering to our indwelling highest consciousness potential, then obstacles, hindrances, blockages, psychic lesions, and such are dissolved. This drawing back of consciousness inside (pratyak-cetanadhigamo'py) reunites the conscious principle (cit) as it was exteriorized or distracted and brings it back from its wandering distractions to break up obstacles and realize fruition -- Self knowing Self --  as homage to the infallible implicate guide/teacher which awaits us all as an innate ever-present wisdom. This practice is a two way street -- redirecting (pratyak) light and consciousness (cetana) to Seed Source -- Seed Source shining forth and permeating our embodiment (Beingness) -- and back from embodiment to Seed Source, in a pulsating motion (vibration or spanda). When the obstructions of the  pathways (antarayah) is cleared out, then the natural flow as natural innate wisdom can be brought forth and manifest. This flow or divine pulsation (spanda) is actually non-dual, neither exclusively "from" Seed-source (crown) to embodiment and manifestation (muladhara), nor exclusively from embodiment (muladhara) to eternal unborn Seed-source, but rather simultaneously "Both/And" as the pulsation of the union of pure Being and pure Consciousness (Sat-Chit-Ananda). This is one way we "re-mind" the small (self) and limited mindset of the greater reality of the greater holographic whole (Self) or purusa found deeply embedded within the heart of each being.

These practices (pratyak-chetana) of redirecting the consciousness to Seed-source not only removes obstacles (antarayah), but thus allows the inner light (wisdom)  to illumine our lives and such becomes expressed even more in All Our Relations. The more the inner light illumines the path, the more the obstacles fall away. At the end all is seen as various forms of Self knowing Self -- love loving love -- in All Our Relations

Since the mind follows the energy and the energy follows the mind, redirecting the mind interiorly (pratyak-chetana) in advanced hatha yoga and laya yoga practices involves the redirection of the cit-prana (energy and consciousness) back to it's inward seed source. This recapturing of the wandering mind and essential energy (cit-prana) then can be utilized to remove (abhava) inner obstructions and blockages (antarayah) of the energy channels (nadis) thus further maturing the physical body as an open and fit receptacle for evolutionary consciousness (siva/sakti).

Now begins the practices which remove the obstacles, disturbances, and distractions of the citta allowing entrance into absorption into the deeper and more continuous experience of samadhi (Sutras 30-51)
