All cravings are the mind seeking salvation or fulfilment in external things and in the future as a substitute for the joy of being. As long as I am my mind, I am those cravings, those needs, wants, attachments, and aversions, and apart from them there is no “I”except as a mere possibility, an unfulfilled potential, a seed that has not yet sprouted. In that state, even my desire to become free or enlightened is just another craving for fulfilment or completion in the future. So don’t seek to become free of desire or “Achieve” enlightenment. Become present. Be there as the observer of the mind. Instead of quoting the Buddha, be the Buddha, be “the awakened one”, which is what the word Buddha means.
Humans have been in the grip of pain for eons, ever since they feel from the state of grace, entered the realm of time and mind, and lost awareness of Being. At that point, they started to perceive themselves as meaningless fragments in an alien universe, unconnected to the Source and to each other. Pain is inevitable as long as you are identified with your mind, which is to say as long as you are unconscious, spiritually speaking. We are primarily talking about emotional pain, which is also the main cause of physical pain and physical disease. Resentment, hatred, self pity, guilt, anger, depression, jealously, and so on, even the slightest irritation, are all forms of pain. And every pleasure or emotional high contains within itself the seed of pain, its inseparable opposite, which will manifest in time.
