Eight yoga forms

1. Karma Yoga: Work and duty. This is the most important of all. The Earth is like a factory, and you are here to do your job: working to fulfill your destiny. You must do it honestly, trying the right way, and you must do it on time, before you die. Both your actions and the results of those actions are karma. Helping and serving others on this path is one important way to trascend the ego-based self spelled with the lowercase s and realize the higher Self spelled with the uppercase S.
2. Hatha Yoga: Physical practice, including asanas and pranayama. Your scientifically create balance and health within the body, then mantain it.
3. Raja Yoga: Mental processes and rational thought; the intellect. You use your mind to get the right guidance, bringing your emotions under control and putting less emphasis on sensory, external perceptions. Raja means "royal", and this introspective, meditative form of yoga is sometimes called the royal path.
4. Vedanta Yoga: Philosophical grounding, including the sharing of thoughts and ideas. This form of yoga helps you to understand your purpose and destination. One of its most essential teachings is that we humans are divine, that "the individual is none other than God." Veda can be translated as "knowledge", and anta means "end"; Vedanta is an applied philosophy or practice -a way of knowing through experience- that goes beyond where mere knowledge ends.
5. Bhakti Yoga: Devotional practice. Here the yogi seeks out and comes to see the Divine in all people and in all creations of the universe. This form of yoga includes formal worship, praying and surrender to God. Jesus and Gandhi, for example, were bhakti yogis who showed their loving devotion in every single action and thought of their daily lives.
6. Mantra Yoga: Chanting and using sound to help achieve peace and calm. A mantra is a word or phrase that you chant or repeat silently to yourself when meditating (doing this is called japa). Mantra Yoga helps you to set your intention and to focus your attention. But it is also very much like a prayer, calling forth Divine power, so it aids in devotion as well (in the beginning mantras were taken only from the Vedas or scriptures). The importance of mantra comes from the ancient belief that the universe came to be created through sound.
7. Jnana Yoga: The way of attained wisdom; often the path of a sage or scholar. (Literally, Jnana means "knowledge"; Ajnana means "ignorance.") This form of yoga requires not just countless years of study but also a great strength of will; it is considered a very advanced path, for more experienced yogis rather than the masses.
8. Laya Yoga: The imagination, esoteric ideas and abstract thought. What is the fifth dimension? What if there is life on Jupiter? These are questions for which there are not yet any definitive answers. Laya Yoga concentrates on the mind's ultimate capabilities and, to reach them, yogis must learn to break down ordinary limitatios and mental conditioning. This often involves meditation and tapping into the chakras, the cosmic energy centers in the human body.
