Usually, when people hear the term Yoga, many of them associate it with various physical exercises where they need to twist, turn and stretch their body in complex ways that are known as Asanas, but this is only one type of Yoga, called “Hatha-Yoga”. In reality, Yoga is an umbrella term for various physical and mental exercises that lead to the overall well-being of a person.By origin, Yoga has mainly five forms:1. Raja Yoga - The realization of divinity through intense meditation2. Karma Yoga – The realization of divine bliss through your own daily activities and duties3. Hatha Yoga – The realization of divine well-being through various physical exercises4. Jyana Yoga – The realization of inexplicable bliss in the pursuit of knowledge5. Bhakti Yoga – The realization of ecstasy through love and devotion for your Personal GodThe purpose of all Yogas is to set your consciousness lose into the vast domain of the unknown, where your brain circuits simulate various fascinating mental states that are usually unimaginable and unattainable in your everyday consciousness. But the whole yoga thing has nothing to do with God or something of that sort. It is all about various states of the human mind.
