There are sixty-four categories of devotional service by performance of which one can rise to the gopīs' stage of unconditional devotion. Affection for Kṛṣṇa on the level of the gopīs is called rāgānuga, spontaneous love. When one enters into a spontaneous loving affair with Kṛṣṇa, there is no need to follow the Vedic rules and regulations.
There are various kinds of personal devotees of Lord Kṛṣṇa in the transcendental abode. For example, there are servants of Kṛṣṇa like Raktaka and Patraka and friends of Kṛṣṇa just like Śrīdāmā and Sudāmā. There are also parents of Kṛṣṇa, just like Nanda and Yaśodā, who are also engaged in the service of Kṛṣṇa according to their respective transcendental emotions. One who desires to enter into the supreme abode of Kṛṣṇa can take shelter of one of such transcendental servitors. Then, through the execution of loving service, one can attain transcendental affection for Kṛṣṇa. In other words, the devotee in this material world who executes loving service in pursuance of the activities of those eternal associates with Kṛṣṇa also attains the same post when he is perfected.
