The actual quote is from the book, Light On Yoga, by B.K.S. Iyengar, in the first paragraph under Yogasanas. Note, some of the words in the title were changed in the following quote.
” The practice of Asanas without the backing of Yama and Niyama is mere acrobatics.”
Most people in America think yoga is only poses and that is false. A valid question, how could living ethically and self disciplines affect yoga practice? Yoga is a process of true self realization. This process could take decades with constant right yogic practice. In the short term, I believe when a student of yoga follows ethical living and the self disciplines, the negativity of the mind and body start to exit. The mind and body will become purified and clearer. For example, If a person who ate and drank only junk food all their lives and then started eating healthy food, their body and mind would start to purify and become health. This lifestyle would improve their bodies ability; hence, yoga practice. Right thinking, right living, right disciplines brings healthy energy which causes self transformation over time.
So ethical living is 1) non violence. 2) truthfulness 3) non stealing 4) non hording
5) committed relationship or celibacy. When one examines each one, it will be discovered, for example, non violence, means more than refraining from physically harming. There are internal thoughts which could be harmful, or the purchase of an item where an animal was mistreated or forced labor.
There are five disciplines, 1) non attachment 2) cleanliness 3) dedicated training 4) study of religious text 5) surrendering to God. Start with the religion you were born into.
