Devotional service with attachment can be executed in two ways—externally and internally. Externally the devotee strictly follows the regulative principles beginning with chanting and hearing, while internally he thinks of the attachment which attracts him to serve the Supreme Lord. Indeed, he always thinks of his special devotional service and attachment. Such attachment does not violate the regulative principles of devotional service, and a real devotee adheres to these principles strictly; yet he always thinks of his particular attachment.
Since all the inhabitants of Vrajabhūmi, Vṛndāvana, are very dear to Kṛṣṇa, a devotee selects one of the inhabitants and follows in his footsteps in order to be successful in his own devotional service. A pure devotee who is attached to the Lord always follows in the footsteps of a personality of Vrajabhūmi. It is advised in Bhakti-rasāmṛta-sindhu (1.2.294) that a pure devotee attached to devotional service should always remember the activities of a particular inhabitant of Vraja, even though he is not able to live in Vrajabhūmi or Vṛndāvana. In this way he can always think of Vrajabhūmi and Vṛndāvana.
The confidential devotees attached to the service of the Lord are divided into several categories: some of them are servants, some are friends, some are parents, and some are conjugal lovers. In devotional service with attachment, one has to follow a particular type of devotee of Vrajabhūmi. In Śrīmad-Bhāgavatam (3.25.38) the Lord says:
- na karhicin mat-parāḥ śānta-rūpe
- naṅkṣyanti no me 'nimiṣo leḍhi hetiḥ
- yeṣām ahaṁ priya ātmā sutaś ca
- sakhā guruḥ suhṛdo daivam iṣṭam
"The word mat-para is only used to refer to persons who are satisfied with the idea of becoming My adherents alone. They consider that I am their soul, I am their friend, I am their son, I am their master, I am their well-wisher, I am their God, and I am their supreme goal. My dear mother, time does not act on such devotees."
