Pain and pleasure - two sides of the same coin
Pleasure is the opposite of pain - and like all opposites, they have no existence without each other. You cannot enjoy pleasure without suffering, without pain. It is significant that ancient Hindu scriptures used the same word, pain, to imply both pleasure and pain - because pain is the ultimate result of both.
The root of pain and pleasure are the same; it is the same sensation with two names. If you have ever received a good massage from a friend or a professional, you will realize that the same massage would seem like sheer physical violence if you received it at the hands of a stranger!
Bliss is that which arises when you drop the ideas of both pleasure and pain. And you have to drop them both together; there is no other way. Bliss is what floods you when both and pain and pleasure have ceased to disturb you. Bliss is beyond pain and pleasure. It is perfect harmony, complete inner silence, total peace.
If you try to understand the truth of your experience, it will be that 'pain' does not exist at all. Pain has only a negative existence. Like darkness, it is only an absence - the absence of awareness. As darkness disappears of its own accord when light is brought into a room, pain dissolves automatically when the energy of your awareness is focused upon it.
You can use your pain as a tool to enter your being. You will find that pain itself can become a door to ananda - bliss.
A small story:
Two men, one a wise man and the other an ordinary person, were traveling through a forest on a dark, moonless night. Suddenly, a shaft of lightning flashed in the sky.
The ordinary man began to tremble in fear. A storm! His mind was immediately caught in confusion: Should he continue to walk? Or should he find a safe place to stop till the storm was gone? He began wishing that he had never decided to undertake the journey. He cursed himself as foolish and unlucky. In other words, he fell headlong into suffering with just a few strokes of lightning!
The wise man, on the other hand, simply used the moments of lightning flashes to take a better look at the road ahead and kept moving. He ensured that he was traveling in the right direction, thanked the lightning for its help, and moved onward.
Pain is just like this flash of lightning. You have no control over its existence. But whether you suffer from it, or learn from it, is entirely up to you! Then, you will realize that you are the cause of your own pain, and only you can be the solution.
