HH Bhakti Vidya Purna Swami in this video: "The Vedic concept is that one's lifestyle and one's philosophy, that should be consistent. Otherwise then one's life and one's values may be different, and that will cause disturbance on the mind, in the intelligence and in one's identity, and therefore will cause social unrest. So the Vedic concept is that we should be simple in our living, but very elevated in our thinking and development of the mind."
