There are those who posit the Universe is real and God is not, viz.; “there is no such thing as a soul”, blah, blah, blah. Such persons are firmly centred on their experience, that is, the experience delivered by the senses, the karmendriyas. See, hear, touch, taste, smell, like this. They are ignorant of the other senses, the jnanendriyas, the internal senses of knowledge. There is much to be known, by which, all else is known, as Vasishtha hints.
