Tantra is not an a priori category, which can be decoded and articulated.

Rather, it is a creation of the human mind that assumes

many guises for many purposes.

It is a processual network of signification, vast and diverse within which is great contradiction as well as realms of convergence.

It is a network in which the players are as diverse as the doctrines that they are exploring ranging from the most austere to the most licentious.

In constructing the cognitive network that constitutes Tantra these authors draw upon their

own experience,    
  intellectual presuppositions,  
   

and social and professional goals

in order synthesize and elaborate the diverse set of

      beliefs,
    practices,  
  rituals,    
and texts     that comprise Tantra.
E ach of them has a very different way of characterizing and elucidating the intricacies of Tantra that is based upon their individual subject position--where they place themselves in relationship to the category.
