Ramanuja's Commentary
Lord Krishna is declaring that the higher and lower natures of prakriti or
material nature both are constituted as His dual nature in the material
existence. This dual nature consists of chit or sentient and achit
insentient categories. This dual nature is the basis and foundation for all
existence sentient and insentient. This dual nature is the power which
designs and models according to qualifications all forms and potencies from
the highest material entity, being Brahma to a blade of grass. This dual
nature is the matrix for all intelligent and non-intelligent configurations
and manifestations. This dual nature solely manifests from Lord Krishna and
constitutes the substratum of all material things. He alone is the
originator, the manifestor, the projector and the retractor of the total
creation by only a fraction of His will.
This dual nature of chit and achit being the collective compound of all
creation exists within the complete nature of the Supreme Lord as merely an
infinitesimal fragment of the total. This is given in sruti and smrti or
revealed Vedic scriptures as evidenced in the Subala Upanisad:II beginning
mahan avyak ta liyate aksharam tamasi liyate which means:The mahat or
primal manifestation revolves back into avyakta the unmanifest, avyakta
manifests into akshara the supra subtle invariable substance, akshara
devolves into tamas the primordial undifferentiated basic substratum of the
original prakriti which is complete darkness. This is a homogeneous
refraction of nebulosity substratum existing as a diametrical reflection of
the nebula within the Supreme Being.
What is described by Lord Krishna as prakriti in its dual forms of chit and
achit as well as the atma or the soul all merge into paramatma the Supreme
Soul and paramatma is source and the support of all manifesting from the
highest as an emanation from the Supreme Lord Krishna as eulogised in all
the Vedas and Vedantas. In as such as He is the cause of the cause of all
things and the source of the source of all beings and in as much as He is
the Supreme Controller of all that is sentient and insentient and in as
much as He is Supreme Power energising and maintaining all existence,
possessing phenomenally glorious attributes and astonishing amazing
qualities; Lord Krishna is paramount and superior to everything with
nothing existing beyond Him and nothing existing separate from Him. Nor is
there any God or demigod, or any other being in existence who possesses
even a fraction of His attributes and qualities nor does any being have the
competence to even imitate His imperishable cosmic potencies.
