The first person I studied for relaxation techniques was Herbert Benson with his book, The Relaxation Response, which was written in 1975. His information is very easy to follow and brings a world of calming techniques for the reader. Presently, he is the founder President of Mind/Body Medical Institute . His present book is The Breakout Principle. Both books are available at Amazon.
My favorite teacher about stress reduction is Dr. Brian Luke Seaward. His book entitled Stand Like Mountain Flow Like Water is among my textbooks that I keep available for use at moments of stress so that I can remember to check if my ego rather than my soul is engaged in handling a life problem.
Another book I keep in my arsenal to keep a calm, peaceful outlook is Kim Thomas. The book of hers that I use most frequently is Simplicity: Finding Peace by Uncluttering Your Life.
Several blogs help me to stay focused on being part of the solution in life. I keep them on my RSS reader to check frequently for tips to help me with my life. My favorites include life hacks.
LifeHack.org is a Daily digest and pointers on productivity, getting things done and lifehacks.
Lifehacker recommends the software downloads and web sites that actually save time. Don’t live to geek; geek to live.
