For iron to be attracted by a magnet is natural. Similarly, for all living entities to be attracted toward Kṛṣṇa is natural, and therefore the Lord's real name is Kṛṣṇa, meaning He who attracts everyone and everything. The typical examples of such attraction are found in Vṛndāvana, where everything and everyone is attracted by Kṛṣṇa. The elderly persons like Nanda Mahārāja and Yaśodādevī, the friends like Śrīdāmā, Sudāmā and the other cowherd boys, the gopīs like Śrīmatī Rādhārāṇī and Her associates, and even the birds, beasts, cows and calves are attracted. The flowers and fruits in the gardens are attracted, the waves of the Yamunā are attracted, and the land, sky, trees, plants, animals and all other living beings are attracted by Kṛṣṇa. This is the natural situation of everything in Vṛndāvana.
(Srimad Bhagavatam----7:5:14----purport).

The demons are not clean, either externally or internally. One should always be careful to keep his body clean by bathing, brushing teeth, shaving, changing clothes, etc. As far as internal cleanliness is concerned, one should always remember the holy names of God and chant Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. The demons neither like nor follow all these rules for external and internal cleanliness.
(Bhagavad-Gita----16:7----purport).

The only business is to chant and remember the holy name, fame and pastimes of the Lord and, according to personal capacity, to distribute the message for others' welfare without motive of material gain.
(Srimad Bhagavatam----1:6:26----purport).

Ajāmila remembered the holy name of the Lord, Nārāyaṇa, by merely calling the name of his son Nārāyaṇa, and that gave him a complete opportunity to achieve the highest perfection of life.
(Srimad Bhagavatam----3:9:15----purport).

The real success in life is ante nārāyaṇa-smṛti—remembering the holy name, attributes, activities and form of the Lord at the time of death. Although we may be engaged in the Lord's devotional service in the temple, material conditions are so tough and inevitable that we may forget the Lord at the time of death due to a diseased condition or mental derangement. Therefore we should pray to the Lord to be able to remember His lotus feet without fail at the time of death, when we are in such a precarious condition.
(Srimad Bhagavatam----5:3:12----purport).

The process of devotional service entails hearing, chanting and remembering the holy name, form, pastimes, qualities and entourage of the Lord, offering service according to the time, place and performer, worshiping the Deity, offering prayers, always considering oneself the eternal servant of Kṛṣṇa, making friends with Him and dedicating everything unto Him.
(Sri Caitanya Caritamrta----2:15:107----purport).

One may be a sinful man before chanting the holy name of the Lord, but after taking shelter in the holy name of the Lord and becoming immune, one should strictly restrain oneself from committing sinful acts with a hope that his method of chanting the holy name will give him protection.
(Srimad Bhagavatam----2:1:11----purport).

One who has taken shelter of the holy name of the Lord, which is identical with the Lord, does not have to study Vedānta philosophy, for he has already completed all such study.
(Sri Caitanya Caritamrta----1:7:72----purport).

A well-to-do householder Vaiṣṇava cannot live like a person in the renounced order who completely takes shelter of the holy name. Such a householder should chant the holy name of Kṛṣṇa in the morning, at midday and in the evening.
(Sri Caitanya Caritamrta----3:6:223----purport).
