Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 16

Sanskrit:

नारायणे तुरीयाख्ये भगवच्छब्दशब्दिते ।मनो मय्यादधद् योगी मद्धर्मा वशितामियात् ॥ १६ ॥

ITRANS:

nārāyaṇe turīyākhyebhagavac-chabda-śabditemano mayy ādadhad yogīmad-dharmā vaśitām iyāt

Translation:

The yogī who places his mind in My form of Nārāyaṇa, known as the fourth factor, full of all opulences, becomes endowed with My nature and thus obtains the mystic perfection called vaśitā.

Purport:

In Bhagavad-gītā (7.13) Lord Kṛṣṇa states: “Deluded by the three modes [goodness, passion and ignorance], the whole world does not know Me, who am above the modes and inexhaustible.” Thus the Lord is called turīya, or the fourth factor beyond the three modes of nature. According to Śrīla Vīrarāghava Ācārya, turīya also indicates that the Lord is beyond the three ordinary phases of consciousness, namely wakefulness, dreaming and dreamless sleep. Bhaga-vac-chabda-śabdite indicates that the Lord is known as Bhagavān, or the possessor of unlimited opulences, principally beauty, fame, wealth, knowledge, renunciation and intelligence. In conclusion, one can obtain the mystic opulence vaśitā, or freedom from the modes of nature, by meditating upon the Lord as turīya, the fourth factor beyond those modes. Everything depends upon the favor of the Supreme Personality of Godhead.
