@Gauri03, Mostly, I was listening to the discourses made by Chinmaya or Dayanananda Saraswathi's disciples to digest Mandhokya Upanishad. They visit once a year from wherever their Ashram is in India and do a 5-7 days of discourses with side stories, etc. Normally, it is an hour or a little over an hour discourse per day and the commute is more than the discourse time. I am not sure whether there are online discourses available. If you like to read the interpretation via a book, I am told Swami Gambhirananda's or Swami Nikhilananda's interpretation is probably the best one can read as they rely a lot on Advaita philosophy as both include Adi Shankara's commentary as well. If you are looking for pure translation, you can rely upon Olivelle's or Hume's translation but it would be too hard to just read translation without any interpretation.
