BG Chap 18 - The philosophy of Lord Caitanya

In Bhagavad-Gītā five principal subject matters have been discussed: the Supreme Personality of Godhead, material nature, the living entities, eternal time and all kinds of activities. All is dependent on the Supreme Personality of Godhead, Kṛṣṇa. All conceptions of the Absolute Truth—impersonal Brahman, localized Paramātmā and any other transcendental conception—exist within the category of understanding the Supreme Personality of Godhead. Although superficially the Supreme Personality of Godhead, the living entity, material nature and time appear to be different, nothing is different from the Supreme. But the Supreme is always different from everything. Lord Caitanya's philosophy is that of "inconceivable oneness and difference." This system of philosophy constitutes perfect knowledge of the Absolute Truth.
