Here is Part 1 of a new, short series (5 or 6 parts) on the Mandukya Upanishad, from James Swartz.
This first part talks about the means for obtaining knowledge and the meaning of the word ‘limitlessness’, using the snake and rope metaphor.
(In case you are wondering about the photo, the title of the Upanishad is sometimes claimed to be derived from the Sanskrit ‘maNDa’, meaning ‘a frog’.)
