Eight-Limbed Yoga for Raja Yoga

Raja Yoga practices the eight-limbed system of disciplines which emphasize meditation.
Patanjali's text enumerates the eight "limbs" of yoga practice.  Despite its connotations, in reality, only one of them requires physical postures which are limited primarily to seated positions. The Eight Limbs are:

1)Yama refers to the five "abstentions" or things to abstain from which are violence, lying, theft, (illicit) sex, and possessions.
2)Niyama refers to the five "observances" or the things to do which are purity, contentment, austerities, study, and surrender to god.
3)Asana: The literal meaning is "seat," and was intended to refer particularly to seated positions. With the popularity of Hatha yoga, it came to mean as yoga "postures" too.
4)Pranayama: Refers to the control of pr?na or vital breath
5)Pratyahara  refers to "Abstraction" or those "that by which the senses do not come into contact with their objects and, as it were, follow the nature of the mind." - Vyasa
6)Dharana refers to "Concentration" or focusing the attention on one object
7)Dhyana means "Meditation"
8)Samadhi refers to the Super-conscious or trance-like state which is also known as the state of liberation

This school of thought requires that one attains the highest form of enlightenment which does not reveal the experienced diversity of the world is mere illusion. Instead, in the end, one finds that the everyday world is real. Furthermore, the highest attainment is when one reaches a point where the many individual selves discover itself; there is not one, single universal self shared by all persons.
