The aim of Yogic study as explained by Mahamuni Patanjali is Chittaruttinirodh, i.e. self control of chitta (mind-Intellect-Iness complex) from its deviations.
One of the important steps in this pathway is to adapt four different –approaches/attitudes towards four different types of people or qualities of people.( 1.33)
Patanjali says, develop friendship with happiness or happy people, develop compassion towards un-happiness or those who are suffering, take delight or joy towards virtues or virtuous people, be enquanimous towards vices or people exhibiting negative qualities or to ignore them.
In addition to the above Chitta prasadana Technique, Patanjali also prescribes, (1.34) Prachhardan Vidharanabhyam Wa Pranasya i.e. one should practice retention of breath after forceful expulsion. Patanjali clearly brings about the connection between breath & mind. Working on exhalation & external retention calms the mind.
Bhagvatgeeta mentions the same word ‘Prasad’ for the state of mind. It says( 2.65) Prasade Sarvadukhanam Hanirasyopi Jayate, Prasanna Chetasohyashu, Budhi Paryavatishthate ll i.e.
If we can take care of all our sorrows, a happy state of mind may be achieved as in this state, the cognitive function performs the best !
