Śrīla Bhaktivinoda Ṭhākura presents an astounding analysis of the mahā-mantra based on Śrī Caitanya Mahāprabhu’s Śikṣāṣṭakam. Supporting his presentation by referencing abundant quotes from Vedic literature, he guides the practitioner of bhakti through the successive stages of perfection, from śraddhā (initial faith) to prema (pure love of God). In Bhajana-rahasya-vṛtti, the first ever commentary on this text, Śrī Śrīmad Bhaktivedānta Nārāyaṇa Gosvāmī Mahārāja has expanded on the meaning of each verse. In easily comprehensible language, he illuminates the process of bhajana.
