In these two lectures in English, Sri Velukkudi Krishnan Swami explains the differences in the two major schools of philosophy - Advaitam and Visishtadvaitam. As is to be expected, he concentrates on the principles of Visishtadvaitam more. An excellent primer to those who seek to understand the differences between these two schools of thought.
