In the last two Sutras Patanjali spoke of the Pranava, OM, and the need to concentrate on this.
As I posted earlier all the sounds originate from three places in the human body, Mouth,a-Throat ,u and from the pit of the stomach M.
From the se sounds came words and language,
Language, nay sounds exist with a corresponding image.
When a sound is made an image flashes in or mind.
At times we may not be able to identify these images.
It is wisdom of the Vedas that there is NO Sound without a corresponding image.
The images we do not recognize are those that spring from our unconscious which is Universal Consciousness.
The Mantras and the Japas of these Mantras help one to unleash the human potential.
Words and their meanings can not be separated.
So much so the Great Poet Dramatist Kalidasa opens his Raghuvamsa with this sloka,
”
वागर्थाविव संपृक्तौ वागर्थप्रतिपत्तये|
जगतः पितरौ वन्दे पार्वतीपरमेश्वरौ||
–> I salute the parents of the world, Parvati and Parameswara, who are inseparable like the “vAk” (word) and “artha”(its meaning); to gain expertise in the right understanding of the words and their meanings.”
