Steve, that's a superlative set of lessons.
Thoughts, health, light, music, earthquakes, all such diverse phenomena are governed by vibration.

The most interesting quote of this group of lessons-for me - is in the lesson summaries for #117. Actually I think this is probably the best quote i ever read by yogananda ; for me at least. I'm going to quote it here:
"Unless there is a relativity of vibration there cannot be cognizance of any vibration in the universe. Do you realize how much that statement explains? Anything of what you are cognizant has a relative vibration within yourself. One who is quick to judge evil in other persons has the seed of that evil within himself. The Godlike person of high vibrational tone is always aware of the God-spark in all he contacts, and his magnetic soul vibration draws to greater intensity that vibrational force in those who come within his vibrational range. Everything in creation has a different rate of vibration. The different rates of vibration balanced in the cosmic rhythm produce before us the majestic cosmos."
Why is that quote so important? Because it describes why we have created the reality we witness. It also describes why it is important to surround ourselves with the vibrations of high frequency souls...." The Godlike person of high vibrational tone is always aware of the God-sparks in all he contacts. His soul vibration draws to greater intensity that vibrational force in those who come within his vibrational range."
