Sridhara Swami's Commentary
In summarisation it has been shown in verses 11 and 12 beginning avajananti
mam mudha meaning the fools deride the Supreme Lord. People who worship
demigods and other lesser gods with the hope of getting quick results do
not respect Lord Krishna and regard Him with esteem, thereby the fit into
the class of non-devotees as previously described. But in verse 13
beginning mahatmanas tu mam meaning the great devotees of Lord Krishna are
being described. Those who omit in their lifetime to worship and propitiate
the Supreme Lord Krishna or any of His authorised avatars or incarnations
and expansions as revealed in the Vedic scriptures it is inevitable that
they are bound to samsara or unlimited cycles of birth and death
perpetually.
Here is stated trai-vidya or the knowers of the Rig, Sama and Yajur Vedas
as well as the Atharva Veda are cognisant of the ultimate truth. Because
they study to know the knowledge of the ultimate truth and they are devoted
to the rituals enjoined and prescribed in the Vedic scriptures. Worship of
the demigods as prescribed in the Vedas is still in fact worshipping the
Supreme Lord indirectly as they are His different part and parcels. Yet by
such worship they receive the soma-pah or remnants of such offerings and
from this very act are purified of all dross and cleansed from all taint
and having accumulation of merit and praying earnestly for access to
heaven, as a result of their virtuous deeds they experience excellent,
celestial enjoyments of the demigods for a duration of longevity.
