How? One small thing: Learn Reiki
It's easy to learn.
It's easy to do.
It really works.
There are different approaches to Reiki. The traditional approach focuses on the spiritual (not to be mistaken for religious - Reiki is NOT a religion). Here's a great resource for this style of Reiki: http://www.reiki.org/faq/learningreiki.html
A less traditional approach is offered here: http://reikiawakening.com/practicalreiki No symbols, no rituals - practical and straight forward. If this style is for you, I highly recommend her book "Practical Reiki".
Reiki is not a new age fad. It's a rediscovering of ancient knowledge. Over 2000 years ago Hippocrates said "The natural healing force within each one of us is the greatest force in getting well." YOU can use Reiki to tap into this natural healing force and help yourself, family, friends, colleagues and even your pets feel better.
"Never give up helping others.
We can do no great things;
only small things with great love.
Do not wait for leaders;
do it alone, person to person."
