Persons in full Krishna consciousness transcends the limit of Shabda-Brahman (Range of Vedas and Upanisads)
To engage in dutiful detached activities as explained in Texts 2.50 – 2.51, one must become disinterested in all hopes for sense gratification which are typically promoted in Vedic karma-kanda sections
This verse implies that Arjuna should rise above the calculation of happiness and misery and fight with buddhi (fixed intelligence)
aExample of indifference to Vedic rituals on strength of devotional service — Sripad Madhevendra Puri (study purport)
bNeophyte must follow the ritual, but one must know the goal — Otherwise it is a waste of time. This implies:
Vedic rites and rituals imperative for neophytes: All kinds of prayers three times a day, taking a bath early in the morning, offering respects to forefathers etc.
But one who is fully Krishna conscious becomes indifferent to all these regulative principles because he has already attained perfection
cAnalogy — Karma-kanda section is compared to the dense dark forest of illusion
dWho becomes indifferent to karma-kanda, even though he is an experienced brahmana – one who understands Krishna and his relationship with Krishna
