Three kinds of peoples have right to perform yoga. These are inferior, superior and supreme. Different types of means have been described for these three kinds of practitioner.

Inferior Practitioner: Such practitioner may perform Ashtang Yoga. Yama, Niyam, Ashan, Pranayam, Pratyahar, Dharana, Dhyan, and Samadhi, these are the eight parts of Yoga. Samadhi is the ultimate goal for which the practitioner strives. These parts of Yoga help the practitioner to achieve total restraints of senses. Provision of Ashtang Yoga has been evolved for the entire practitioners because they are beginners on the great path of Yoga. They start practices of yoga in there present birth.

Superior Practitioner: Such kind of practitioner has already perfected the eight parts of Ashtang Yoga in their previous births but could not attain salvation. They are naturally inclined for the practice of Yoga, however they don't have to start right from the beginning. Because of experiences from their previous birth, they instinctively start the practice of Yoga. Thus superior practitioner may attain the state of reconciliation merely through Kriya Yoga that involves penance, the study of Vedas and devotion for God.

Supreme Practitioner: For the supreme practitioners, external means of performing yoga have no meaning. Practice and asceticism are the only means required for such practitioners to attain state of reconciliation and salvation.

Yoga recognises two kinds of asceticism- Apar, Vairagya (simple asceticism) and Param Vairagya (Supreme asceticism). Simple asceticism is in fact a way to achieve supreme asceticism. Supreme asceticism is a state of supreme consciousness.

By practice means making repeated attempts to achieve total restrains of the senses. Contemplation, meditation and reconciliation are the means to achieve perfection in practice.

During the practice of meditation, a state arrives when there is virtually no difference between the contemplator and contemplative. The whole conscience of contemplator appears like the contemplative. This state marks the stage of reconciliation.
