Sutra 2

sutra 2 yogah chitta vritti nirodhah
yogah chitta vritti nirodhah

Translation: Yog is the stilling/blocking of modifications of chitta/mind

The human body has a brain which is controlled by the mind, which can be called the Chitta. The Chitta can be assumed as a connection with the Divine. The level of purity of the Chitta gives us our desires and also our course in life.
The purer the Chitta, the selfless the desires.


Vrittis, which are the various ways in which the mind distracts us, or to say, because of the impurities of the soul and based on its karmas, the vrittis are weaker or strong.
The practice of yog blocks the vrittis from the mind and purifies the connection with the Divine, avidya is banished and reality dawns.
