Hereunder we give you some of the best known and powerful tantric yantras, the mystic diagrams which, when properly concentrated and meditated upon, or trataka practised thereon, bestow both bhukti and rnukti (enjoyment and liberation). We have given the name of the yantra, its mantra, and its presiding deity. Mantra, yantra and devata are the essence of tantra yoga.
Sri Tripura Sundari Dhyanam
She radiates like the aura surrounding the rising sun. She has three eyes and four hands. She holds the pasha (noose of bondage), ankusha (hook), bow and arrow. I meditate on you who is the form of Shiva.
