So this is necessary. Therefore it is said samādhinā, means "Don't manufacture your meditation." Samādhi, this trance by meditation, cannot be attained by something manufacturing. Anu: "Just follow the great predecessor ācārya." Samādhinā anusmara tad-viceṣṭitam. Tat means the acyuta, acyuta, the activities of the Lord. Therefore we have to learn Kṛṣṇa consciousness through the disciplic succession. Our, this sampradāya, the Gauḍīya-sampradāya, is also in the same line-Nārada, Vyāsadeva. Nārada is the disciple of Brahmā. It is, therefore, called, this sampradāya... This party is called Brahma-sampradāya. Brahma-madhva-gauḍīya-brahma-sampradāya. Originally from Brahmā. Brahmā instructed Nārada. You'll find in the Bhāgavata. Brahmā is instructing Nārada. Now you see Nārada is instructing Vyāsadeva. Similarly, Vyāsadeva instructed Madhva Muni.

The six Gosvāmīs instructed Kṛṣṇadāsa Kavirāja. Kṛṣṇadāsa instructed Narottama dāsa Ṭhākura. Narottama dāsa Ṭhākura, Viśvanātha Cakravartī. Viśvanātha Cakravartī, Jagannātha dāsa Bābājī. In this way, there is a clear line of disciplic succession.
