To many people, yoga appears to simply be a physical practice that helps achieve and maintain fitness, assists in the healing of injuries, or aids in stress management. And it is all that, but there is also a lot more to it. Yoga is a combination of physical, spiritual and mental practices that unite the mind, body and spirit. Sure, yoga can start off being physical, working on your strength and flexibility and learning about the poses and sequences. But if you want to advance deeper into the lifestyle of yoga, you cannot avoid the spiritual and philosophical side, which are both interesting and practical.
