Krsna is the Supreme Lord, the original Lord [SB 1.3.28]. Prahlada Maharaja is our guru, and Krsna is our worshipable God. As advised by Sri Caitanya Mahaprabhu, guru-krsna-prasade paya bhakti-lata-bija [Cc 2.19.151]. If we can be successful in getting the mercy of Prahlada Maharaja and also that of Nrsimhadeva, then our Krsna consciousness movement will be extremely successful.
