Huh their forum got post tantric teachings? Anyway I think it is a timely reminder for all people who have yet to be initiated into Tantric practices and yet think they can do these practices without proper guidance from qualified masters...
It is important to note that
tantra without strong view of Emptiness may even lead one towards the lower realms, such as if you do wrathful practices wrongly you may even fall into the ghost realm without the View of Emptiness because you did not transform the emotions (such as desires, anger, and etc) into wisdom, but instead, create even more negative karma in the process.. See E-Sangha topic:
Wrathful Diety Practice, Possible Low Rebirth I think Bohiruci would know more about this topic as he has learnt some of these practices from lamas and rinpoche.. I do not practise tantra and only heard a little.
And worse if one abuses or uses tantra for the wrong purpose or for other personal reasons (some people combine tantra with some other magic/occult practices etc, many other things) other than to attain Enlightenment and to liberate oneself and others, one can even be reborn into the vajra hell, which is the hell specifically for those who have committed against the samaya vows and practised tantra deviantly. This may sound heavy, but it is not, it is just cause and effect, it is karma. So to those interested in tantra please take note and learn under a qualified teacher.
