Is there a yoga-type activity that is not tied to a religion (Buddhism, Hinduism, etc.)?

Anyone can do yoga as it doesn’t involve religion and it is very good for health. But when you do yoga, you should get completely involved in it without thinking of anything else and your mind should be totally in control of things without having any negative thoughts as such. Then, it would be better if you do yoga in the early morning time and in open place as there is pure weather and zero pollution around with fresh air

Im pretty sure that it has something to do with those religions I mentioned..I looked it up

Thanks :)

The uniting together of Intellect and Mind, and all the Senses, and the all pervading Soul is said to be Knowledge of the foremost kind. That Knowledge should be acquired (through the preceptor’s aid) by one that is of a tranquil disposition, that has mastered his senses, that is capable (by meditation) of turning his gaze on the Soul, that takes a pleasure in such meditation, that is endued with intelligence and pure in acts. One should seek to acquire this Knowledge by abandoning those five impediments of Yoga which are known to the wise, viz., desire, wrath, cupidity, fear and sleep.

No man ever attains to success by means other than the acquisition of knowledge, the practice of penance, the subjugation of the senses, and renunciation of everything.

Meditation, study, gift, truth, modesty, simplicity, forgiveness, purity of body, purity of conduct, subjugation of the senses, these enhance one’s energy, which when enhanced destroys one’s sins. By behaving equally towards all creatures and by living in contentment upon what is acquired easily and without effort, one attains to the fruition of all one’s objects and succeeds in obtaining knowledge.

This constitutes the Yoga doctrine, and these aspects belong to every human being irrespective of religion, anything Yoga has its roots into Hinduism or Sanatan Dharma. It is based on eternal principles which apply to all of mankind and not a certain religion or country.
