While there are four suggested ways to realize the Self/God, based on one’s disposition,there is yet another approach the goal of Life,Realization of Self.
This is based on the processes that evolved from following any of the four paths,Gnana,Karma,Raja and Bhakthi Yogas.
One must remember that the term Yoga means Union,that is the union of the individual self with the Universal Self.
Hence there is no question of debating which Yoga is superior.
One follows a Yoga that suits one’s disposition.
While following a Yoga, the processes might vary,though basics remain the same,the tools one develops as he goes along and the processes are as many as there are individual dispositions.
One such process that belongs to this categorization is Tantra.
Tantra finds a place in the Vedas,though they are not stated explicitly.
In Tantra one finds an amalgam of all four yogas.
And there are three processes to Realize self through Sound ,the fundamental principle of the Universe and Abstract Thought.
Mantras,Sounds,
Yantra,Geometrical patterns to facilitate abstract thinking to still Chitta and
Tantra, an amalgam of all yoga and the above two.
The Tantra also uses physical senses to realize Self.
There are innumerable treatises on Tantra Shastra.
I have written on authentic texts to follow in Tantra.
Devi,Shanmugha,Lakshmi,Shiva,Bhairava are some of the Deities invoked.
I have written a few articles on Tantra ,detailing procedures,texts and Deities.

As the subject is vast and complex , I keep updating.
Also, I do not write with a preset notion on what I write.
I write when I feel the urge,the topic presents itself and material pops up as it were.
I write, not that I know much, but I seem to get information at specific time.
It is since a year I wrote on Devised and Tantra.
A reader has been asking a specific intricate question on Tantra for the past year.
I hope I shall answer him through my articles in the present burst.
Hope he reads this article,though his specific query is yet to be answered here.
The Tantra Sastra,though deals with Deities with Form,in essence it is with Principles and Abstract Thought.
The symbolism is Jewel or Flame,Lustre.
These are expressions of experiences which can not be described.
The source for deatils is given below.
