The Eastern Sea integrates the first twenty issues of Laharī (1-20) that contain, among other topics, works of immense literary value, such as: Bhakti-Rasāmṛta-Sindhu (qualities of Kṛṣṇa) written by Rūpa Gosvāmī (1489–1564), one of the six Gosvāmīs and one of the most influential ācāryas of Gauḍīya-Vaiṣṇavism; added to that are such great masterly treatises as the prefaces to the first four Ṣaṭ-Sandarbhas, the most prominent philosophical work of Gauḍīya-Vaiṣṇavism, written by Jīva Gosvāmī (1513-1598), one of the most important Gauḍīya-Vaiṣṇava writers who produced a large number of works on the practice of bhakti, being also one of the six Gosvāmīs of Vṛndāvana and a nephew of Rūpa and Sanātana Gosvāmī. The commentary by Viśvanātha Cakravartī, a great Gauḍīya-Vaiṣṇava (1626-1708) also known as rasika-ācārya, is included, too.

The prefaces to the Sandarbhas were written by Śrī Haridās Śāstrī Mahārājjī (1918-2013, great scholar of Gauḍīya-Vaiṣṇavism who, coinciding with his guru’s wish, went to Benares where he studied Indian philosophy for twelve years, obtaining nine university degrees and three graduate degrees covering the six systems of Indian philosophy and theology.
