Yoga, from the experience I have had, not only brings together human beings, helping us, as David Life put so well, to connect and transcend name, religion, gender, etc., but also helps us to connect to animal-beings and to connect to natural world more deeply. When we are connected deeply to all of life, then we can take action to protect all life, such as eating a vegan diet, and standing up for peace. Yoga shows us that our true identity is integrally connected to the identity of all others.
