Nithyananda of the Life Bliss Foundation may sound, from the names, a bit unrealistic or woo-woo, but he and his lectures are quite excellent and right on.  They are true wisdom.

Free videos on YouTube (3 seconds of ads at the beginning, then can skip):  There are more, so just enter his name and a subject to get to the right videos.  Also, subscribe to his channel.

Note:  He will start sometimes with a few sentences in another language, for the varied audience.

I would recommend you take notes.

I would recommend you spend a whole day (or even a 1/2 day) to immerse yourself in this as if it were a seminar.
