And raja yoga!
Prana Pastime is new to Hinduism. In time, he will come to know everything. At the moment Bhakti, Dharma and Bhagawat Gita. There will be suggestions from other forum members as well.
Raja Yoga is no different from the Ashtanga (Eight faceted) Yoga of Patanjali. Except for a more 'impressive' name (for those who are impressed by names, I am not), it is the same:
1. Yama (The five "abstentions"): Ahimsa (Non-violence, non-harming other living beings), Satya (truthfulness, non-falsehood), Asteya (non-stealing), Brahmacharya (celibacy, fidelity to one's partner), and Aparigraha (non-avarice, non-possessiveness).
2. Niyama (The five "observances"): Śauca (purity, clearness of mind, speech and body), Santosha (contentment, acceptance of others and of one's circumstances), Tapas (persistent meditation, perseverance, austerity), Svādhyāya (study of self, self-reflection, study of Vedas), and Ishvara-Pranidhana (contemplation of God/Supreme Being/True Self).
3. Asana: Literally means "seat", and in Patanjali's Sutras refers to the seated position used for meditation.
4. Pranayama ("Suspending Breath"): Prāna, breath, "āyāma", to restrain or stop. Also interpreted as control of the life force.
5. Pratyahara ("Abstraction"): Withdrawal of the sense organs from external objects.
6. Dharana ("Concentration"): Fixing the attention on a single object (
Aup corrects it. Thought, object of meditation. You have already withdrawn the sense organ from external objects - see next, Dhyana).
7. Dhyana ("Meditation"): Intense contemplation of the nature of the object of meditation.
8. Samadhi ("Liberation"): merging consciousness with the object of meditation.
