Lustful:- it is the state of pleasure and negative emotions, it is a state which works between body and mind. There is little long term attachment and action is done only for the sake of pleasure. Its obsessive. Its taking state.
Loving:- it works between mind and heart. There is an easy acceptance of pleasure but pleasure is of no much importance. there is a kind of long term attachment in that state. You just do it for the love of it and you may not find to fulfill purpose in the action or see if it is good. Its not obsessive. It has a feel good factor. Its give and take.
Meaningful:- it works between heart and the soul. You do loving things that fulfills some purpose and which is good. It is the state of utmost bliss. Its giving state.
The goal should be to move from lust to love & from love to meaning.
first we create illusion of pleasure object if its available, create expectations, then we crave for them, then we act to get them, if satisfied we get temporary pleasure, if not it gives us pain; after a short period we again crave for them, while craving we feel the pain, suffer. so its more of pain than pleasure. most sense gratification harm us in one way or other, either it makes you unproductive, harms health, shift the focus from giving. it should not be an addiction but only be achieved if we wish to get from our heart, value it, truly need them, from the money we have earned through labor, hard work; not from others money, or quick money.
