:::::::::::::You're the one that is putting gibberish on this article! See, "nirvana through sex" is possible... but that's a dangerous advice if (at least one of) the practitioners don't control trsna completely (be free from the "sensuality" fetter). Ok, that quote can stay, only and only if this is added: but taught that they are only appropriate for the most elite practitioners, who had directly realized emptiness and who had unusually strong compassion. If not, it's a dangerous advice to saṃsāraputras that will lead to much dukkha.
