To know through love
Only those who love us get close. It thus makes little sense to imagine that the ways of karma (duty), jnana (intellectualism) and tapasya (austerity) will give us closeness to Krishna (God) beyond just proximity. Therefore every path depends on bhakti (devotion) and in eventuality that bhakti must mature to the pinnacle of Prema-bhakti (unadulterated love). To know is to love and only through love we can know. And so it is said by Divinity Himself: bhaktya mam abhijanati.......Even to know Himself, he came as a devotee exhibiting the highest loving sentiments and thus perceived Himself as never before.
