Coming to his senses, King Indra realized that he was not a very sincere disciple of his spiritual master, Bṛhaspati. Therefore he decided that henceforward he would be niśaṭha, nonduplicitous. Niśaṭhaḥ śīrṣṇa-tac-caraṇaṁ spṛśan: he decided to touch his head to the feet of his spiritual master. From this example, we should learn this principle enunciated by Viśvanātha Cakravartī Ṭhākura:
- yasya prasādād bhagavat-prasādo
- yasyāprasādān na gatiḥ kuto 'pi
"By the mercy of the spiritual master one is benedicted by the mercy of Kṛṣṇa. Without the grace of the spiritual master, one cannot make any advancement." A disciple should never be a hypocrite or be unfaithful to his spiritual master. In Śrīmad-Bhāgavatam (SB 11.17.27), the spiritual master is also called ācārya. Ācāryaṁ māṁ vijānīyān: the Supreme Personality of Godhead says that one should respect the spiritual master, accepting him as the Lord Himself. Nāvamanyeta karhicit: one should not disrespect the ācārya at any time. Na martya-buddhyāsūyeta: one should never think the ācārya an ordinary person. Familiarity sometimes breeds contempt, but one should be very careful in one's dealings with the ācārya. Agādha-dhiṣaṇaṁ dvijam: the ācārya is a perfect brāhmaṇa and has unlimited intelligence in guiding the activities of his disciple. Therefore Kṛṣṇa advises in Bhagavad-gītā (BG 4.34):
- tad viddhi praṇipātena
- paripraśnena sevayā
- upadekṣyanti te jñānaṁ
- jñāninas tattva-darśinaḥ
"Just try to learn the truth by approaching a spiritual master. Inquire from him submissively and render service unto him. The self-realized soul can impart knowledge unto you because he has seen the truth." One should fully surrender unto the spiritual master. and with service (sevayā) one should approach him for further spiritual enlightenment.
