Everything Converges on Feeling (Vedanâ)!

The 3 Kinds of Feeling are:
1: Pleasant Feeling that is agreeable, delightful & likable.
2: Painful Feeling that is disagreeable, repulsive & distressing.
3: Neutral Feeling that is an indifferent neither pleasure nor pain.

The 5 Kinds of Feeling are:
1: Pleasant Bodily Feeling that is agreeable & arised in the body.
2: Painful Bodily Feeling that is disagreeable & arised in the body. 
3: Pleasant Mental Feeling that is agreeable & arised in the mind.
4: Painful Mental Feeling that is disagreeable & arised in the mind.
5: Neutral Feeling that is an indifferent neither pleasure nor pain.

The 6 Kinds of Feeling are:
1: Feeling that is arised from visual eye contact.
2: Feeling that is arised from auditory ear contact. 
3: Feeling that is arised from olfactory nose contact.
4: Feeling that is arised from gustatory tongue contact.
5: Feeling that is arised from tactile skin & body contact.
6: Feeling that is arised from mental mind & ideational contact.

The cause of Feeling is Momentary Sense Contact.
Ceasing of this momentary contact instantly ceases the feeling.
The effect of Feeling is Craving, if the mind is untrained...
Noble Awareness of arising feeling can prevent arising of craving.
All Buddhist training of mind control aims at this crucial purpose:
To break the automatic emergence of craving, when feeling arises!  

If the feeling is pleasant arises craving towards the object...
Pleasant feeling is therefore the cause of desire, lust & greed!
If the feeling is painful arises craving away from the object...
Painful feeling is therefore the cause of aversion, anger & hate!
If the feeling is neutral arises craving for neglect of the object...
Neutral feeling is therefore the cause of ignorance, & confusion!

Since ignorance, greed and hate are the three roots of all Evil and
their absence are the three roots of all Freedom it verily confirms:
Every state and all experienced phenomena converges on Feeling...
