Method of Protecting the Body by the Namokar Mantra

OM ... Origin of Mantras

The twelfth verse of the Shraman Sutra describes how Om is the essence of the Namokar Mantra,
'Arihanta Asrira Airiye Uvajjhaya Munino Panchakhar Nippano Omkaro Panchparamitthi'.
The initial letters of the names of the five divine personalities combine to make Om or Aum according to the following formulation: Arlhant - A
Asharirl (Siddha) - A
Acharya - A
Upadhyaya - U
Muni (Sadhu) - M
A +A +A=A... 3 A sounds combine to make A
A+U=0O ... A and U combine to make O
O+M=OM or Aum
Om is the base. It is the mother and source of all sounds. When chanting Om, we are also chanting the Namokar Mantra. When chanting the Namokar Mantra, Om is there, everywhere. Om is the original sound. Om represents the three main forces in nature, A stands for creation, U for preservation and M for destruction.
According to the particular power of the sound, or the combination of sounds, a mantra will have an effect of creation, preservation or destruction. The Narmokar Mantra basically uses the destructive force since without the destruction of bad karma nothing beneficial can be attained.
Namo Arihantanam, Namo Airiyanam, Namo Loe Savva Sahunam have destructive power. 
The Namokar Mantra also includes the powers of creation and preservation. Through the mantra, one can attain divine knowledge and samadhi, which is the blissful state of self - realization. The divine knowledge of Namo Uvajjhayanam is representative of creation. And the samadhi of Namo Siddhanam represents preservation.
Om can be used as a shorter form of the Narmokar Mantra, as can Arhum or A, Si, A, U, Saya Namah.

The Arhum Yoga Logo

In order to describe the meaning of the Arhum Yoga logo, we must describe the meaning of Om, Hreem and Arhum. These three interrelated sounds symbolize the techniques and the aim of Arhum Yoga. They symbolize knowledge of the external, the internal and the Supreme. They are Right Knowledge (Arhum), Right Faith (Om) and Right Conduct (Hreem). Visualize the picture of Hreem, Om, Arhum. First on the outside is Hreem; this is the universe, nature and the five elements. Embedded in this lies Om whose positive energy moves in one direction to the Supreme, completely and wholeheartedly. In the center there is an unmoving flame of fire burning brightly. This is Arhum, the power of the soul. It is the Arihant, the soul in its perfected state. The meaning is that you are the universe or Hreem. Your entire energy is Om, and your soul realizes its highest state of perfection, Arhum. By this system you can know the world, you can see how energy moves and you can see your Self, how all powers awaken. Watch and arouse yourself. Sound is the base of this knowledge. When you see Reality, then you will understand that this is the complete picture of the Supreme - omniscient, omnipresent and omnipotent.
