Yoga is often a great way to concentrate on things happening now instead of the future. This is important because the future is something that doesn't always go according to plan. Issues need to be dealt with one day at a time. Thinking about the future can put pressure on a relationship, which can lead to a problem that could have been avoided.
The principles of Yoga are universal to all religions. As a result of this, anyone, of any religion, can see the link to Yogic principles and their religion. There is no need for religious conversion, or indoctrination, at any Yoga teacher training, to accept spiritual dogma.
