Nrshima Caturdasi

Sri Sthanu Narasimhadeva of Mayapur holds a special place in the hearts of devotees worldwide, known for His divine pastimes and boundless mercy as Bhakta Vatsala, the transcendental protector of devotees.

“I offer my respectful obeisances unto Lord Nrisimhadeva, the source of all power. O my Lord who possesses nails and teeth just like thunderbolts, kindly vanquish our demon-like desires for fruitive activity in this material world. Please appear in our hearts and drive away our ignorance so that by Your mercy we may become fearless in the struggle for existence in this material world.”
(SB 5.18.8)

To prove that the statement of His servant Prahlāda Mahārāja was substantial — in other words, to prove that the Supreme Lord is present everywhere, even within the pillar of an assembly hall — the Supreme Personality of Godhead, Hari, exhibited a wonderful form never before seen. The form was neither that of a man nor that of a lion. Thus the Lord appeared in His wonderful form in the assembly hall.
(SB 7.8.17)
