You can’t describe the flavour and sweetness of honey until you have tasted it. It’s a bit like that with Yoga. You have to try it.
One won’t be able to embrace it on an intellectual level only, it is definitely a physical experience. Regardless of which aspect of Yoga you are practicing, may it be postures, breathing exercises or meditation, it will always be your whole body which is responding and evolving in some way or another. Yoga will always be experiential.
One of the Buddhist teachings explains that truly deep insight only happens when something has been understood on a physical level. Yoga is the perfect expression of this idea: It often happens that at the end of a practice one is suddenly gaining an insight into an issue, which could be even unrelated to the practice just completed. Responsible for this is the even and free energy flow created by practicing, freeing up blockages in the body, not only physically, but also emotionally and mentally, leaving you feeling balanced with a wonderful sense of harmony.
