Yoga's most profound philosophy is based on eight basic principles that mirror all it's sense:

According to the Yoga Sutras of Patanjali, one of the ancient texts that is the basis for the philosophy behind yoga, there are the eight “ashtangas” (sanscritic) of yoga. Each "ashtanga"- limb relates to an aspect of achieving a healthy and fulfilling life, and each builds upon the one before it. You may be surprised to hear that only one of the limbs involves the performance of yoga postures. Here is a description of the eight "ashtangas":

1. Yama: Five ethical guidelines regarding moral behavior towards others:

Ahimsa: Nonviolence

Satya: Truthfulness

Asteya: Nonstealing

Brahmacharya: Nonlust

Aparigraha: Noncovetesness

 

2. Niyama: Five ethical guidelines regarding moral behavior towards oneself:

Saucha: Cleanliness

Santosa: Contentment

Tapas: Sustained practice

Svadhyaya: Self study

Isvara pranidhana: Surrender to God

 

3. Asana: Practice of yoga postures.


4. Pranayama: Practice of breathing exercises.


5. Pratyahara: Withdrawal of the senses, meaning that the exterior world is not a distraction from the interior world within oneself.


6. Dharana: Concentration, meaning the ability to focus on something uninterrupted by external or internal distractions.


7. Dhyana: Meditation. Building upon Dharana, the concentration is no longer focused on a single thing but is all encompassing.


8. Samadhi: Bliss. Building upon Dhyana, the transcendence of the self through meditation. The merging of the self with the universe. Sometimes translated as enlightenment.
