(Prahlad Maharaj pacifies Lord Nrsimhadeva with prayers)
"In the Nṛsiṁha Purāṇa, Lord Nṛsiṁhadeva says: 'Anyone who prays unto Me and takes shelter from Me becomes My ward, and I protect him always from all sorts of calamities.'"
(Nectar of Devotion, Chapter 11)
"When Lord Nṛsiṁhadeva appeared, Prahlāda Mahārāja was never afraid of Him, whereas his atheist father was immediately faced with death personified and was killed. Therefore, although Lord Nṛsiṁhadeva appears as death for an atheist like Hiraṇyakaśipu, He is always kind and is the reservoir of all pleasure for the devotees like Prahlāda. A pure devotee is not, therefore, afraid of birth, death, old age and disease."
(Kṛṣṇa Book, Chapter 87)
"Let me offer my obeisances unto Lord Nṛsiṁha-deva, who is always enlightening Prahlāda Mahārāja within his heart and who always kills the nescience that attacks the devotees. His mercy is distributed like moonshine, and His face is like that of a lion. Let me offer my obeisances unto Him again and again."
(Śrīdhara Svāmī's prayer quoted in CC Madhya 8.5, Purport)
"I offer my respectful obeisances unto Lord Nṛsiṁha-deva, the source of all power. O my Lord who possess nails and teeth just like thunderbolts, kindly vanquish our demonlike 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."
"Anyone who remains unagitated, even in the presence of cause for agitation, is called dhīra, or equipoised. The Supreme Personality of Godhead, being always in a transcendental position, is never agitated by anything. Therefore someone who wants to become dhīra must take shelter of the lotus feet of the Lord. In Bhagavad-gītā (2.13) Kṛṣṇa says, dhīras tatra na muhyati: a person who is equipoised in all circumstances is never bewildered. Prahlāda Mahārāja is a perfect example of a dhīra. When the fierce form of Nṛsiṁha-deva appeared in order to kill Hiraṇyakaśipu, Prahlāda was unagitated. He remained calm and quiet, whereas others, including even Lord Brahmā, were frightened by the features of the Lord."
(Śrīmad-Bhāgavatam 5.17.20, Purport)
"The material world is full of envious persons, but if one frees himself of envy, he becomes liberal in his social dealings and can think of others' welfare. Anyone who takes up Kṛṣṇa consciousness and engages himself completely in the service of the Lord cleanses his mind of all envy (manaś ca bhadraṁ bhajatād adhokṣaje). Therefore we should pray to Lord Nṛsiṁha-deva to sit in our hearts. We should pray, bahir nṛsiṁho hṛdaye nṛsiṁhaḥ: 'Let Lord Nṛsiṁha-deva sit in the core of my heart, killing all my bad propensities. Let my mind become clean so that I may peacefully worship the Lord and bring peace to the entire world."
(Śrīmad-Bhāgavatam 5.18.9, Purport)
"The Supreme Personality of Godhead in His transcendental form of Narahari, Nṛsiṁhadeva, is always ready to kill the demons, who always create disturbances in the minds of honest devotees. To spread the Kṛṣṇa consciousness movement, devotees have to face many dangers and impediments all over the world, but a faithful servant who preaches with great devotion to the Lord must know that Lord Nṛsiṁhadeva is always his protector."
(Śrīmad-Bhāgavatam 7.8.51, Purport)
"The devotees can always remember the form of Nṛsiṁhadeva when they are in danger, and therefore the appearance of Nṛsiṁhadeva was not at all inauspicious. The Lord's appearance is always worshipable and auspicious for all sane persons and devotees."
(Śrīmad-Bhāgavatam 7.9.14, Purport)
"So we should always consider that this material world is a dangerous place and therefore we shall chant Lord Nrsimha's Holy Name in order to be protected by Him in all dangers."
(Srila Prabhupada Letter, July 4, 1970)
"Regarding my health, I am improving by the grace of Krishna. Thank you very much for taking so much care of my health for praying to Nrsinghadev. He is very kind. By all your prayers He will surely take care of me. Kindly follow all rules and regulations. That will give you spiritual strength. We should always be in touch with Krishna the Supreme Personality of Godhead directly. That is by chanting Hare Krishna."
(Srila Prabhupada Letter, September 3, 1974)
