Nothing brings more pain than too much pleasure meaning. Life is all about balance and harmony, and too much of anything is not good for you. When you experience pleasure all of the time or you are always demanding this sensation this can cause you to become numb, always needing to reach greater heights and never finding satisfaction with the current status quo. Life will have ups and downs and we have to take the good with the bad, the sour with the sweet. Over time too much pleasure will cause over stimulation and this can lead to significant pain. Be satisfied with what you have, don't spend all of your time trying to reach greater levels of pleasure when you should be happy with the life that you have. We all have bad moments and days as well as good ones and I is important to learn to accept this so that your life is balanced.
