The Importance of Sanskrit Alphabet:
Sanskrit alphabet is considered to be of Divine nature. It is eternal and indestructible. Comprised of the 51 letters (a to kṣa), called akṣaramālā (the Garland of Letters), it encompasses all aspects of creation sustenance and dissolution.
The 16 vowels and 35 consonants of the Sanskrit alphabet are reflected in our body as the seats of various cosmic powers and reside in the lotus petals of the 6 chakras.
Invocation of Seats of Cosmic Powers
These seats of cosmic powers are activated and invoked during the chanting of each one of the letters with a concentration on their position in the body. Furthermore, this process of invocation can also be combined with a particular mantra.
Ṣaṭcakra Japa
Mantra japa (chanting) is normally done for a minimum of 108 counts and multiples thereafter. This is known as one mala. Using a rosary, which contains 108 beads, is one way to complete one mala, another way is by utilizing a technique called ṣaṭcakra japa.
This method involves mapping of the Sanskrit letters on the petals of the six cakras while adding a prefix and suffix of the letter to the mantra. In other words, the mantra itself is sandwiched or [bracketed] between 2 letters.
An example of this would be: aṁ [śrī matre namaḥ] aṁ
This way of chanting increases the power and effectiveness of that mantra many times over. The power of this practice comes from:
remembering the letter and its location on the body,
seeing the color of the cakra petal,
hearing the sound of the letter,
remembering to put the letter before and after the mantra
