I like reading from the devirahasyam tantra bala patala
One should place "Shakti" (Sauh) at the end of 'Vagbhava" (Aim) and "Kamaraja" (Klim), ending this with Namah. O Devi, this is the eight lettered Mantra of Bala...
Dakshinamurti is the Seer, Pankti is the Metre for pronunciation, the Goddess if Tripura-Bala, "Aim" is the Seed, "Sauh" the Shakti. "Klim" is the linchpin. Its application is towards Dharma, Artha, Kama and Moksha.
ऐं क्लीं सौः बालायै नमः
I meditate on Bala, clothed in red, with a digit of the Moon as Her ornament, effulgent as the rising sun, with three eyes, holding a book and a rosary, showing the gestures of removing fear and giving, seated on a red lotus.
