sva-pada-mule patitam tam arbhakam
vilokya devah krpaya pariplutah
utthapya tac-chirsny adadhat karambujam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When Lord Nrsimhadeva saw the small boy Prahlada Maharaja prostrated at the soles of His lotus feet, He became most ecstatic in affection toward His devotee. Raising Prahlada, the Lord placed His lotus hand upon the boy’s head because His hand is always ready to create fearlessness in all of His devotees.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The necessities of the material world are four — ahara, nidra, bhaya and maithuna (eating, sleeping, defending and mating). In this material world, everyone is in fearful consciousness (sada samudvigna-dhiyam), and the only means to make everyone fearless is Krsna consciousness. When Lord Nrsimhadeva appeared, all the devotees became fearless. The devotee’s hope of becoming fearless is to chant the holy name of Lord Nrsimhadeva. Yato yato yami tato nrsimhah: wherever we go, we must always think of Lord Nrsimhadeva. Thus there will be no fear for the devotee of the Lord.
