We have to work according to our capacity; at the same time chant Hare Krsna mantra. Krsna has given you the tongue, and there is no difficulty. Kurvana yatra karmani. And always think of Krsna, man-mana bhava mad-bhaktah. “How I can think of Krsna constantly? It becomes hackneyed.” No. The varieties. Krsna says that you think of Krsna while drinking water, you think of Krsna when you see the sunshine, think of Krsna when you see the moonshine, day and night. So at daytime there is sunshine, at night there is moonshine. So day and night you can think of Krsna. So, so many ways… Krsna-siksaya, bhagavac-chiksaya, as is taught in the Bhagavad-gita, you think of always Krsna, then your life is successful. Man-mana bhava mad-bhakto mad-yaji mam namaskuru [Bg 18.65].

So therefore bhakti-yoga means vairagya-vidya [Cc Madhya 6.254]. You have to stop thinking of this material bhukti, mukti, siddhi. Simply you have to think of Krsna. That is spiritual platform. That is instructed here. Try to follow, and your life will be successful.
