Ashtanga (eight limbs of yoga) Ashtanga, the eight limbs of yoga, is Patanjali's classification of classical yoga, as set out in his Yoga Sutras. He defined the eight limbs as yama (abstinences), niyama (observances), asana (postures), pranayama (breathing), pratyahara (withdrawal), dharana (concentration), dhyana (meditation) and samadhi (absorption). The eight limbs form a sequence from the outer to the inner. Postures, important in modern yoga, form one limb of Patanjali's scheme; he states only that they must be steady and comfortable.
1. Yamas (RESTRAINTS) This first limb, Yama, refers to vows, disciplines or practices that are primarily concerned with the world around us, and our interaction with it. While the practice of yoga can indeed increase physical strength and flexibility and aid in calming the mind, what’s the point if we’re still rigid, weak and stressed-out in day-to-day life? There are five Yamas : Ahimsa (non-violence), Satya (truthfulness), Asteya (non-stealing), Brahmacharya (right use of energy), and Aparigraha (non-greed or non-hoarding).
2. Niyama (OBSERVANCES) The second limb, Niyama, usually refers to duties directed towards ourselves, but can also be considered with our actions towards the outside world. The prefix ‘ ni ’ is a Sanskrit verb which means ‘inward’ or ‘within’. There are five Niyamas : saucha (cleanliness), santosha (contentment), tapas (discipline or burning desire or conversely, burning of desire), svadhyaya (self-study or self-reflection, and study of spiritual texts), and isvarapranidaha (surrender to a higher power).
3. A sana (POSTURE) The physical aspect of yoga is the third step on the path to freedom, and if we’re being honest, the word asana here doesn’t refer to the ability to perform a handstand or an aesthetically impressive backbend, it means ‘seat’ – specifically the seat you would take for the practice of meditation. The only alignment instruction Patanjali gives for this asana is “ sthira sukham asanam ”, the posture should be steady and comfortable.
4. Pranayama (BREATH CONTROL) Generally translated as breath control, this fourth stage consists of techniques designed to gain mastery over the respiratory process while recognizing the connection between the breath, the mind, and the emotions. As implied by the literal translation of pranayama , "life force extension," yogis believe that it not only rejuvenates the body but actually extends life itself. You can practice pranayama as an isolated technique (i.e., simply sitting and performing a number of breathing exercises), or integrate it into your daily hatha yoga routine.
Pratyahara, the fifth limb, means withdrawal or sensory transcendence. It is during this stage that we make the conscious effort to draw our awareness away from the external world and outside stimuli. Keenly aware of, yet cultivating a detachment from, our senses, we direct our attention internally. The practice of pratyahara provides us with an opportunity to step back and take a look at ourselves. This withdrawal allows us to objectively observe our cravings: habits that are perhaps detrimental to our health and which likely interfere with our inner growth. 5. Pratyahara (Sense withdrawal)
6. Dharana Dharana means ‘focused concentration’. Dha means ‘holding or maintaining’, and Ana means ‘other’ or ‘something else’. Closely linked to the previous two limbs; dharana and pratyahara are essential parts of the same aspect. In order to focus on something, the senses must withdraw so that all attention is put on that point of concentration, and in order to draw our senses in, we must focus and concentrate intently. Tratak (candle gazing), visualisation , and focusing on the breath are all practices of dharana, and it’s this stage many of us get to when we think we’re ‘meditating’
7. Dhyana (MEDITATION) Meditation or contemplation, the seventh stage of ashtanga, is the uninterrupted flow of concentration. Although concentration (dharana) and meditation ( dhyana ) may appear to be one and the same, a fine line of distinction exists between these two stages. Where dharana practices one-pointed attention, dhyana is ultimately a state of being keenly aware without focus. At this stage, the mind has been quieted, and in the stillness it produces few or no thoughts at all. The strength and stamina it takes to reach this state of stillness is quite impressive. But don't give up. While this may seem a difficult if not impossible task, remember that yoga is a process. Even though we may not attain the "picture perfect" pose, or the ideal state of consciousness, we benefit at every stage of our progress.
8. Samadhi (PURE CONTEMPLATION) Samadhi is oneness with the subject of meditation. There is no distinction, during the eighth limb of yoga, between the actor of meditation, the act of meditation and the subject of meditation. Samadhi is that spiritual state when one's mind is so absorbed in whatever it is contemplating on, that the mind loses the sense of its own identity. The thinker, the thought process and the thought fuse with the subject of thought. There is only oneness, samadhi.
