Whoever, with assiduousness, desires to worship whichever form he relishes, I make that devotional affinity of his firm, unswerving.
Krishna makes his observation with regard to plural ways of worship of people in general. He does not draw any line of distinction and dissuade the devotees from worshipping in the ways and manners they cherish. Worship should gain its place and importance in the society, and more and more people should embrace the devotional path and pursuit. To this end, Krishna does what is best.
Whoever wishes to worship any deity or divine source he prefers, Krishna says, can rightly do so. It is worship that matters. Faithful worship should be encouraged and strengthened. It is unwise to preach superiority or inferiority in worship. Faithfulness and attention are alone the determining factors in doing worship, and each selects the object of worship according to his inner preference.
Krishna wishes to help worshippers in intensifying their devotion. For this, he stabilizes their worship, leading it further, causing no conflict to anyone concerned. Worship is for the growth of the worshipper and not for the benefit of the worshipped.
