For thousands of years, long before there was such a thing as a science of chemistry, people were fascinated by plants, because they knew that plants contained substances that could affect people.

My lectures, based on Islamic teachings, were on various subjects. Some of the titles were, 'The Intoxication of Life,' 'The Purpose of Life,' 'The Real Cause of Man's Distress,' 'The Journey to the Goal in Life,' and, one of my favorites, 'The Heart of Man.' They contained important insights that spoke to something deep inside me.
