[b]I, 2 Yogah citta vritti nirodhah
Yoga
is experienced
in that mind
which has
ceased
to identify itself
with its
vacillating waves of perception.[/b]
M. Stiles
Based on Iyengar’s and Sw. Satchidananda’s commentary, citta (consciousness) is composed of three aspects:
i. manas: mind; the part which collects information using the senses
ii. buddhi: intellect; the part that discriminates and discerns
iii. ahamkara: ego
Sw. Satchidananda provides an excellent example which demonstrates these three aspects: You are sitting quietly and peacefully. But then your quietness is disturbed by the perception of a smell. Manas recognizes the sensation of a smell. Buddhi identifies the smell as tasty Swiss cheese. Ahamkara then decides to eat some of the tasty cheese.
The vacillating waves of perception (vritti) are those that give rise to the desire that disturbs the peaceful state; in the example above, it is the perception and identification of the smell which leads to the desire to eat some cheese. Once the desire is satisfied, the peaceful state returns.
To quote Sw. Satchidananda:
?The entire outside world is based on your thoughts and mental attitude. The entire world is your own projection. Your values may change within a fraction of a second. … If you feel bound, you are bound. If you feel liberated, you are liberated. Things outside neither bind nor liberate you; only your attitude towards them does that. … That is why Yoga does not bother much about changing the outside world.? (p. 5).
?So if you can have control over the thought forms and change them as you want, you are not bound by the outside world. … If you control your mind, you have controlled everything. Then there is nothing in this world to bind you.? (p.6)

Comments by Helen Barker:
I K Taimni ? One of the most important and well-known Sutras - it defines with the help of only 4 words the essential nature of Yoga. ?The full significance of the Sutra can be understood only when the subject of Yoga has been studied thoroughly in all its aspects?.
Bernard Bouanchaud says that, ?The other aphorisms will not be properly understood unless they are approached in relation to this one.?
