Svadhyaya (self-study) is an important part of the yogic journey, so rather than tell you about yoga in my words, here are a few resources that may help you explore yoga a little further on your own.   If you are looking for something specific, please contact me.  I may be able to make a relevant suggestion, as this list is just a few of my favorites.

• The Heart of Yoga by TKV Desikachar 
• Yoga & the Quest for True Self by Stephen Cope
• Yoga The Iyengar Way by Silva, Mira & Shyam Mehta
• Viniyoga Therapy for low back, sacrum and hips or Upper back neck and shoulder therapeutic care by Gary Kraftsow
• Key Muscles of Hatha Yoga by Ray Long
• Calling the Spirits by Sean Johnson and the Wild Lotus Band (music cd)
• The Yoga Sutras of Patanjali translated by Sri Swami Satchidananda

There are helpful articles at www.iayt.org/ the International Association of Yoga Therapists   

There are nice, free meditations at UCLA's Mindful Awareness Research Center site  http://www.marc.ucla.edu/body.cfm?id=22&oTopID=22

That's a starter list, enjoy your journey into this ancient wisdom.  Please contact me with any questions or book suggestions you may have for me! 

Never be afraid to ask a question, especially of yourself.  Discovery is the mission of life.
