Then it is self-apparent you have never achieved a meditative state, which is infinitely more blissful by definition.
That's surprising, considering I have hundreds of hours of yoga and I'm a daily practitioner of
Ericksonian meditation for over seven years.
Maybe I've been doing it wrong this whole time? Or perhaps you shouldn't go around making assumptions about internet strangers.
I don't have to assume anything when you have stated all the information necessary to reach such a conclusion, unless you are a liar.
If sex is the ultimate nirvana, then why is tantric sex (axiomatically) more blissful?
Edit: Yes, meditation can simply be calming, even significantly so. But this calming feeling is infinitely different from a meditative state. There is absolutely no mistaking a meditative state. The primary difference is that one achieves a meditative state at the instant the perception of one's "self" disappears entirely. I'm particular with my language, and to say a meditative state is "infinitely" more blissful is a poignantly chosen phrase, and in no way euphemistic. There are no boundaries invoked by a self in which the bliss can be contained, and accordingly the bliss is "non-finite" or infinite.
Edit 2: I would possibly concede to a semantic distinction between "pleasurable" and "blissful" whereupon sex could be described as more pleasurable, but certainly not more blissful or 'heavenly.'
