Pranaam!
I have to agree that sexual indulgence is enjoyment of the senses. It is the strengthening of kama vasana - the innate desires for sex.
For all these past lives we have enjoyed the senses as donkeys, dogs and other beasts. This life, we use the opportunity of having the manushya- human body for the devotion to God.
Because kama vasna (sexual desire), is the strongest of all, we have been permitted to enter marriage and lead a disciplined sexual life and not be slave to the senses. Obviously there will be occassions when we are not in control of ourselves - but through intense devotion AND regulation of our sexual instincts, the kama vasna will be destroyed.
I mean think about it. Essentially it is a physical process which ultimately has a profound effect on our spiritual progress by strengthening of the kama vasna.
No shastras preach indulgence OR suppression of sexual instincts for that matter.
What they do teach is sublimation - we cannot possibly expect to overcome sexual desires without devotion, japa, dhyan and the grace of God....but as long as we are attached to enjoying the senses, we cannot fully experience the bliss of devotion to God. Therefore, what Abhi was practicing was suppression NOT sublimation - semen has to be sublimated by intense bhakti.
Please, let us not try to deny the fact that sexual life must be regulated in grihastha ashram. There are times of the month and days (such as ekadashi) when we must adopt strict control.
Do you not agree that sexual desire is the stringest of impressions/vasna (together with desire for wealth, taste and power)?
If so, should we not be making every effort to sublimate it rather than let it attach us (as atman) to the body?
