Vedanta

Vedanta means the "end of Vedas", and is an ancient Indian system of inner science based on the three kinds of scriptures, i.e., "Upanishads" (which are the part of the Veda where philosophical discussions about the Supreme Self are expounded - there are supposed to be 108 Upanishads, among which the number of major ones is only ten), "Brahma Sutra", and the renowned "Bhagavad Gita", a chapter of Mahabharata.

Contrary to common sense, Upanishads don't expound in any way the ritualistic aspects of Vedas (these aspects are propounded in the first part of the Vedas), but only seek the inner truth exclusively in a philosophical manner. In this sense, Vedanta is an epitome of Jnana Yoga, and Shankaracharya, the founder of Advaita Vedanta completely denies all rituals, and even has a rather negative attitude towards meditation as a spiritual practice, and says that human being can get enlightened only when they obtain the real, experiential knowledge that their real self (Atman in Sanskrit) is nothing but the Universal Self (Brahman in Sanskrit), and that rituals (and possibly meditation as well) exist only for the people who are not yet ready to abandon mundane things to go to this supreme truth. In this sense, spiritual seekers who cling to their body or vital force and indulge themselves in Hatha Yoga (Yoga of Body) or in psychic power, would be regarded as not yet ready to acquire the Real Knowledge.
