Srimad Bhagavad-Gita :
Chapter-12. ( Bhakti-yogam)
Slokam - 3 & 4.
ye tvaksharamanirdesyam avyaktam paryupasate,
sarvatragamacintyam ca kutasthamacalam dhruvam.
sanniyamyendriyagramam sarvatra samabuddhayah,
te prapnuvanti mameva sarvabhutahite ratah.
indriyagramam samniyamya = contolling all sense-organs as necessary;
sarvatra samabuddhayah = exclusively and with maximum balanced mind;
sarvabhutahite ratah = taking care and interest towards the welfare of complete living things;
ye tu = one who;
arvatragam acintyam = all-pervading and unimaginable ( inconceivable );
kutastham acalam = in the center and immovable;
dhruvam anirdesyam = permanent ( fixed ) and indefinite;
avyaktam aksharam = unmanifested and which is beyond the perception of the senses ( Brahmam )
paryupasate = practice Upasana;
te mam eva prapnuvanti = they attain Me only.
So it has been established that the devotees who with full faith focus their minds on the Supreme Lord Krishna and offer bhakti or exclusive loving devotion to Him are the most superior.
But what about the other votaries of the Vedic culture who follow the path of worshipping the imperishable brahman or the spiritual substratum pervading all existence which is unmanifest being imperceptible?
What are there rewards? This Lord Krishna elucidates in these two slokam-s.
In the Bhagavat Purana, the attribute of imperceptibility has been ascribed to illusion because it is acintyam or inconceivable and incapable of being rationalized although it is able to be perceived by some advanced beings.
The word aksharam is not referring directly to the Supreme Lord but rather to His impersonal unmanifest aspect known as the imperishable brahman or spiritual substratum pervading all existence.
In the very beginning there was neither existence or non-existence, there was neither superior elements or inferior elements.
Then there existed only tamas or the obscurity of darkness and within this obscurity alone was the unmanifest, inconceivable, ever renewable and was none other then prakriti the material substratum pervading physical existence which is imperceptible, possessing no distinctive attributes to distinguish her by.
