However, despite disdain and disgust for such acts, unlike Judeo-Christian-Islamic-Zoroastrian faiths, there's no "eternal damnation" for homosexuals or lesbians in Eastern, especially Indian spirituality. For, Bhagavatam (4.29.29) states:
"The Self which is enveloped by ignorance, is sometimes embodied as a man, sometimes as a woman, sometimes as a homosexual. According to its deeds and the nature one acquires thereby, one may be born as a god, a human or a beast."
This rather easy going approach is owing to the fact that the sages, yogis and free mystics of ancient India have never been bound to one centralized religious order or ordinance as such. From the beginning of time, seekers in India have been encouraged to seek and find The "Sanatan" (Eternal) Truth, for and by their own-self; a la any Buddha.
"The pleasures that are born out of sensory contacts are sources of pain. They certainly are transient, having a beginning and an end. The intelligent man is wise enough not to indulge in them." - (Bhagavad Gita)
The emphasis herein has been to "overcome" this hold of sensory, therefore, illusory world, we find ourselves in. Over the ages, realized beings of India discovered The Natural Order of Things That Be. They found that essentially, appearance of phenomenal world becomes the seeming reality for us only as far our normal sensory perceptions are concerned. It is possible for any "son" born of The Heavenly "Father" and Our Divine "Mother"; that is, a manifest physical entity here; namely, a human being, to "meet" The Primordial Parent Source - God, of the less metaphysically versed. These seekers, by any name, spiritual or scientific, yet are free mystics -- by any way and means, open-mindedly searching for The First Principle.
And, what's "That" Eternal Principle which governs All Which Is?
It is The Natural Order of What Is. It permeates all, as each and every-thing-ness. There is no "thing" as such and nothing in much, that exists without or outside it. It's the life "matter" of everything, latent or manifest.
Because Judeo-Christian-Islamic faiths think of IT as a physical entity, the god of their ancestors; they are unable to rise above a limited vision of reality. Others view IT as a spirit and some otherworldly being; but even this is a conceptual entity than the eternal reality.
Cutting to the chase, this "Eternity" of Godliness in us, yogis find, is a "virginal" sentient immanence, unto and as whatsoever there be. From "It" emanates phenomena "seen" and unseen. This "Father-Mother', Alpha-Omega of Root Principle of All That Is, cannot be reached if naturally flowing mystical and karmic forces within our being are perversely disturbed. These ill-advised adverse actions include anal and oral sex; with the latter is meant intake of semen in one's mouth. The mouth is given to eat and take the Name of "That" Divineness which mothers all. Yogis call this divine energy "living and breathing" in us, as "Serpent" Power within -- "Kundalini". If this serpentine energy is ill-treated, it may boomerang; rendering a person psychically damaged, sometimes beyond repair. In other words, thus being the case, one would not become self-realized or enlightened; and, hence, would remain bereft of Salvation or Nirvana -- as one would be perpetually engaged in these "nether" activities that would bother or block all attempts to reach "There".
It is from this Universal Self that homosexuality is found to be unacceptable and contrary to natural order, and, plain-simply, unnatural by even the most mystically evolved beings; though they may prefer to remain, maybe uneasily, silent about it. But most do come forth clearly about it, if pushed.
Homosexuality is abhorred by many faithful and religious people because they find unpalatable the idea of man mating with man or a woman with her own sex. They think of it as an unholy alliance. It would not only breakdown the traditional social structure but could well lead to dissolution of age-old system of marriage, lead to considering sanctioned sex with animals, even with children in future. Some perverts may even advocate incest as an "internal l family" matter. Where does it end?
However, without beating around the bush, it is clear that spiritual beings, whether of a "lower" faith and religion as such or of an evolved philosophy, are somehow, deeply and devastatingly but "naturally" appalled by homosexuality. They consider homosexuality a devious, political gain obtained by its proponents in today's time.
As far as a-religious but secular mystics are concerned, homosexuality may be a preferred lifestyle of some, but even they find nothing spiritual in it. It's a sexual orientation that has no sanction in mystical spheres. That's the sad truth. Let there be no doubt about it.
As long as homosexuality is kept up as their personal lifestyle and not claimed as an acceptable spiritual living too, it's a state of affairs of other people, which, a law abiding but God-fearing citizen may well have to bear with; grinding one's teeth, maybe: or, smiling it away sagaciously.
After all, everybody has the right to go to hell in one's own way.
