It is the withdrawal from a heavy addiction:
your mind is an addict which has depended on the senses for aeons, not
only in this life. If you think cigarettes are hard to give up, or heroin,
try giving up the entire domain of pleasure which is dependent on the
senses and existence in general.”
Excerpt From
The Only Way to Jhāna – Ajahn Nyanamoli Thero
If you begin to know
and see the sense organs clearly, and sustain that clarity, you will begin
to diminish your ignorance with regard to them—your appropriation of
them, your assumption of ownership. You will then begin to understand
that resisting them is futile, and therefore your aversion will also fade.”
Excerpt From
The Only Way to Jhāna – Ajahn Nyanamoli Thero
So, you can come to realise that your own senses are where the problem
is; but you cannot see this without first being withdrawn from sense
objects. For as long as you are still engaging and acting out of their pressure
reacting to the person who upset you – you will maintain the notion
that the sense objects are the problem. And this is exactly the root
misconception: you don’t see your body for what it is, i.e. these sense
organs that you resist, which, in turn, is why you delight in sense objects
of an agreeable kind, and why you’re averse to sense objects of a disagreeable
kind. Because, fundamentally, you don’t want to have to deal
with or face the voidness of those sense organs, that lack of substance,
because doing so reveals your non-ownership of them.”
