chitta manasa nivritti - control of mind

                                     why we control the  mind?
As the mind is capable of perceiving both happiness & unhappiness, we should try to  train the mind to perceive and feel both these dualities as equal entities.

originally our mind needs everlasting happiness,which is next to impossible to get in materialistic plane. thats why so many seers and thinkers since olden ages, scripted some sutras to retrograde the mind in to another plane of consciousness ----
where the mind subdued to a state of non-reactiveness
where the mind is not identifying with ego
where the mind has no vrittas of thoughts
where the mind looses its identity
where the mind perceives that the whole universe as single entity
where the mind vanishes in to unknown para pakriti -- - - - 
                    
    to get rid of un happiness, to get rid of despair, to remove grief,
    to remove sorrow in society
    to love all & serve all
    to engulf in happiness -- - -  man strives hard and passes  frontier to frontier and project himself in differen planes of consciousness by doing different yogic kriyas.
