There seems to be a relation between daily-life behaviour of a person and movements associated with his private parts.

These movements can be internal, can be external. Eg. are hardening during sleep, release of harmones(knowingly or unknowingly). Even the fluctuations in hardness seems to depict deep thoughts-with-behaviour of person, like egoistic speech, greedy thinking pattern etc.... whose stored force(in form of sankharas, probably) gives fluctuations in hardness.

I tried to find on internet, couldn't find. Are there any chapters dealing with such knowledge in tipitaka(of any tradition)?

(this time, it's not a challenge, rather a query.)

There is evidence that an arahant has undergone such transformation in body chemistry that he has gone beyond the dichotomy of masculinity and femininity. All normal physiological sexual functions seem to be atrophied in an arahant as it is said that seminal emission is impossible for an arahant even in sleep.32 We may also note the tradition maintaining that arahants never dream,33 maybe because they have attained such perfect mental health that there is no necessity to release tension through dreams.

Nibbåna As Living Experience (Lily de Silva)

The footnote is a reference to the Vinaya, in the section "allowance for a sitting-cloth (Vin 1.295)":

Thus it is, Ānanda, thus it is, Ānanda, that when they fell asleep, thoughtless, careless, impurity was emitted as the result of a dream. Ānanda, those monks who fall asleep calling up mindfulness, careful, by these impurity is not emitted; and, Ānanda, those who are ordinary people, passionless in regard to pleasures of the senses, by these impurity is not emitted. It is impossible, it cannot come to pass, Ānanda, that impurity should be emitted by one perfected.”

  • Interesting Vinaya, which I have some slight skepticism towards. Not all nocturnal emissions come from sexual dreams. See link: medicalnewstoday.com/articles/321351.php#facts-and-myths Commented Feb 2, 2020 at 2:01
  • At suttacentral.net/pli-tv-bu-vb-pj1/en/brahmali, a sleeping arahant monk had an erection due to wind and was mounted by two females. There was "moisture" visible to the other monks. So this story is saying the "moisture" is from the ladies??? Commented Feb 2, 2020 at 2:15

When it is stiff because of sensual desire: for one oppressed by sensual desire, the penis becomes erect.

When it is stiff due to feces: for one oppressed by feces, the penis becomes erect.

When it is stiff due to urine:for one oppressed by urine, the penis becomes erect.

When it is stiff because of wind: for one oppressed by wind, the penis becomes erect.

When it is stiff because of being bitten by caterpillars: when bitten by caterpillars, the penis becomes erect.



In this, I'm not discussing any particular attainment, but: After 50 odd years practising Theravada, including some 20 odd years in a Forest environment, during which there was the endless fear of erection, I unwittingly developed techniques for reversing the energy flow back to the origin of sensation, based on [mis]conceptions of Kundalini. The upshot of which is that whilst recently having returned to lay status and thus permitted relationships in accord with the third precept - Kamesu micchacara - I am now permanently incapable of erection.

  • What about nocturnal emissions? Thanks Commented Feb 2, 2020 at 1:48
