You might consider Yog as a particular religion. However, it is a universal religion for all the sects of people from the world. It preaches guiding principles for healthy and pious living, positive attitudes, study of sacred texts, and communion with the Supreme God. Although some branches of Yog might seem more religious or mystical. Be clear that Yog itself is not any religion.
Yog as a universal religion in itself is open to all cultures and religions. It encourages you to understand and respect all religious and spiritual texts so that you understand yourself and others in positive and deeper ways. Yog is never biased, prejudiced, or exclusive. So, in order to have the opportunity of Yog practice, you need not be a Hindu, a Buddhist, a Muslim, a Christian, or a Jew, but you may be from any of sects. Whichever religion you have been following since your birth, Yog will certainly help you to reveal your spiritual potential.
