How happy is the little stone
That rambles in the road alone,
And doesn't care about careers,
And exigencies never fears;
Whose coat of elemental brown
A passing universe put on;
And independent as the sun,
Associates or glows alone,
Fulfilling absolute decree
In casual simplicity.
In order to understand why one chooses to be a Tantric practitioner, there has to be an understanding of cause and effect, cyclic existence, the awareness that the reality that we think we are seeing is not reality as it really truly is. So enlightenment is seeing reality with bare awareness, non-conceptual reality.
A unifying factor between the different traditions and lineages of Tantra, is that it is feminine in nature. It acknowledges the feminine as the basis from which all the practices spring. Therefore, Tantra is by its nature, the understanding that all phenomenal existence, the universe, or cosmos, that we experience is feminine in nature.
There are Tantrics who deliberately break taboos and social norms and then there are other Tantrics who, by means of their practices and the way that they practice, that to society in general, it may have the appearance of breaking social norms but in fact that is just the manifestation of the progress of their practice.
