As you may notice, I moved the thread to "Paths and meditation techniques." I was not sure where to put this thread, but kundalini did not seem like the right place for it.
On this subject, I began the daily practice of meditation almost 40 years ago, and I was also celibate at the same time, and at the same time I found ecstatic altered states of consciousness, so there might be a correlation between the two. Nonetheless, I later entered into sexual relationships without losing my access to the ecstasies; however, the distractions that come with relationships did have an impact upon the frequency, duration, and therefore intensity (depth) of my ecstasies.
Over the years I have engaged in celibacy, and almost exactly 12 years ago I took it up again and remain with it, and following that I also intensified my contemplative practices to see how deep I could go in the ecstasies. About a year after that I had one sexual encounter with a contemplative who had more attainment than anyone else I had met. But, it did not turn into a relationship, nor did I experience a loss of the fruit of the contemplative life.
In the religious literature of the world religions there is some literature on celibacy. It is often presented that if the celibate ever broke their celibacy once, then all of their attainments would be lost and they would have a long hard climb back up the "mountain." Well, that was not my experience. My meditations were not disturbed in the least by one sexual encounter with a woman with almost as much attainment as myself.
However, I would argue that there are a number of people on the contemplative journey who are sexual predators. I would count Rajnish and Choigum Trungpa on this list. We find nothing in their literature that suggests that they had anywhere near the attainment that most of us here are reporting. So, I believe there is something to restraint, and there can be something gained in complete sexual abstinence. But, one need not fear one, or infrequent, transgressions of any kind, if one's life is mostly oriented toward an ethical, self-aware contemplative life. I believe this is the middle path between self-abusive, suppressive, religious practices verses licentiousness.
