antaryāmī, bhakta-śreṣṭha,--ei dui rūpa
śikṣā-guruke-the spiritual master who instructs; ta'-indeed; jāni-I know; kṛṣṇera-of Kṛṣṇa; sva-rūpa-the direct representative; antaryāmī-the indwelling Supersoul; bhakta-śreṣṭha-the best devotee; ei-these; dui-two; rūpa-forms.
One should know the instructing spiritual master to be the Personality of Kṛṣṇa. Lord Kṛṣṇa manifests Himself as the Supersoul and as the greatest devotee of the Lord.
Śrīla Sanātana Gosvāmī is the ideal spiritual master, for he delivers one the shelter of the lotus feet of Madana-mohana. Even though one may be unable to travel on the field of Vṛndāvana due to forgetfulness of his relationship with the Supreme Personality of Godhead, he can get an adequate opportunity to stay in Vṛndāvana and derive all spiritual benefits by the mercy of Sanātana Gosvāmī. Śrī Govindajī acts exactly like the śikṣā-guru (instructing spiritual master) by teaching Arjuna the Bhagavad-gītā. He is the original preceptor, for He gives us instructions and an opportunity to serve Him. The initiating spiritual master is a personal manifestation of Śrīla Madana-mohana vigraha, whereas the instructing spiritual master is a personal representative of Śrīla Govindadeva vigraha. Both of these Deities are worshiped at Vṛndāvana. Śrīla Gopīnātha is the ultimate attraction in spiritual realization.
