After one regularly performs the processes of hearing and chanting and after the core of one’s heart is cleansed, smaraṇam, remembering, is recommended. In Śrīmad-Bhāgavatam (2.1.11) Śukadeva Gosvāmī tells King Parīkṣit:
yogināṁ nṛpa nirṇītaṁ
“O King, for great yogīs who have completely renounced all material connections, for those who desire all material enjoyment and for those who are self-satisfied by dint of transcendental knowledge, constant chanting of the holy name of the Lord is recommended.” According to different relationships with the Supreme Personality of Godhead, there are varieties of nāmānukīrtanam, chanting of the holy name, and thus according to different relationships and mellows there are five kinds of remembering. These are as follows: (a) conducting research into the worship of a particular form of the Lord, (b) concentrating the mind on one subject and withdrawing the mind’s activities of thinking, feeling and willing from all other subjects, (c) concentrating upon a particular form of the Lord (this is called meditation), (d) concentrating one’s mind continuously on the form of the Lord (this is called dhruvānusmṛti, or perfect meditation), and (e) awakening a likening for concentration upon a particular form (this is called samādhi, or trance). Mental concentration upon particular pastimes of the Lord in particular circumstances is also called remembrance. Therefore samādhi, trance, can be possible in five different ways in terms of one’s relationship. Specifically, the trance of devotees on the stage of neutrality is called mental concentration.
