Getting started
In the 2nd chapter of the Yoga Sutras of Patanjali, Patanjali states that in order to get started in your practice one should follow the path of Kriya Yoga. Kriya Yoga is the yoga of action and is comprised of three parts: Tapas (burning zeal / excitement), Svadhyaya (self-study) and Isvara Pranidhana (surrender of the results of your practice to a higher power / God). The three tiers of Kriya Yoga help us to eradicate our afflictions so that we can meditate more easily and therefore approach a state of Samadhi.
