Pleasure and Pain
There cannot be pleasure without pain. If you experience great moments of pleasure, be prepared to experience great moments of pain, the pain is just waiting around the corner. If you are detached, if you are insensitive, if you do not feel pleasure or pain, then it takes away the joy of the experience, then it makes the experience mechanical and pointless. The experience of pleasure and pain is an endless cycle. Taking yourself out of this cycle is like taking yourself out of the experience. If you wish to partake in the experience, you must accept both pleasure and pain, they go hand and hand.
Either you take yourself out of the cycle or you learn to engage in the experience and truly accept both pleasure and pain. Learn to find joy in both experiences. Pain and suffering becomes a moment of growth, a preparation for the experience of pleasure. Like the sun and the rain, enjoy both experiences, the sun is naturally very beautiful, you need to find the beauty in the rain and learn to appreciate it, the beauty in rain is more hidden. If someone you love brings pain within you, learn to appreciate this pain, be thankful that the person has even given you the opportunity to love.
