By expansion of his knowledge of the Supreme Brahman, he had already attained liberation from the bondage of the body. This liberation is known as nirvāṇa. He was situated in transcendental bliss, and he continued always in that blissful existence, which expanded more and more. This was possible for him by continual practice of bhakti-yoga, which is compared to fire because it burns away all dirty, material things. He was always situated in his constitutional position of self-realization, and he could not see anything else but the Supreme Lord and himself engaged in discharging devotional service.
