Please accept my humble obeisance. All glories to Srila Prabhupada
Those who chant the holy names of the Lord should follow the following eight rules:
(a) They should keep firm faith in the words of guru and Çästra.
(b) They should associate with devotees who are engaged in chanting the holy names.
(c) They should perform bhajana by hearing and chanting the kåñëa-kathä spoken by saintly persons.
(d) Following the above rules will result in anartha-nivåtti. In the kingdom of sädhana, a practitioner must follow these four basic processes of bhajana.
(e) Those who chant the holy names must have undivided attention when they chant.
(f) They should chant the holy names according to the taste of their personal relationship with the Lord.
(g) They should be attached to chanting the holy names.
(h) In this way, they will attain bhäva-bhakti, the preliminary stage of love of God, which is also called permanent rati.
