Religion is a social organization and embodiment of a Spiritual practice.

Technically, not necessary, but that would be like saying, technically, humans do not need 'each other' or need 'education' In reality, we do, immensely. When we don't have it wee seek it out learning ans religion, couched in different terms.

A good example is 'Yoga'. Yoga is 100% a religious practice, it's Hatha Yoga, a subdomain of Hinduism. Yoga exists to help prepare the body to be enlightened, specifically via the Kundalini Fire.

By removing the direct, religious language from Yoga, it's promulgators hoped to make it more amenable and acceptable to Westerners and it has been. (I do Yoga myself).

But merely changing the words to make them 'not seem religious' doesn't really change the underlying religious practice.
