When a person is firmly fixed in devotional service to the Supreme Personality of Godhead, he is described as vīra-vrata, fully determined. Such a devotee increases his ecstasy in devotional service more and more. Thus as soon as he remembers Lord Viṣṇu, his eyes fill with tears. This is a symptom of a mahā-bhāgavata. Dhruva Mahārāja maintained himself in that devotional ecstasy, and Śrī Caitanya Mahāprabhu also gave us a practical example of transcendental ecstasy when He lived at Jagannātha Purī. His pastimes there are fully narrated in Caitanya-caritāmṛta.
