Before explaining the significance of Om, it is extremely important to understand the meaning of the word ‘Om’. The sound of Om is all pervading in the entire universe which is the force of life and its presence renders energy to the words. This is the form and beauty of Om.
Pronunciation of the word Om consists together of three sounds. Meaning of these sounds is well explained in the Vedas and according to it, the word is pronounced as well.
This all pervading sound has been considered equivalent to God who is omnipresent in this formless eternity. Thus, knowing Om means knowing god. All the Vedas explain the significance of Om. The essence of Om has been established by so many ideologies. The glory of the divine is inherent in the accomplishment of creation, continuance and cataclysm. Thus, experiencing the happiness of soul is also possible through it. Chanting of all the Vedic mantras end only with Om and thus, the Vedic hymns remain incomplete without pronouncing the Om. This Om is the indicative mantra of all the materialistic, divine and spiritual peace. Introducing the life theory, the relationship between the sound of Om and life has been explained.
By embracing Om, one can gain knowledge. A person gets rid of thousands of sins and attains liberation by contemplating Om through penance and meditation. It is also called ‘Pranav Mantra’. It is the imperishable sound of this universe and it has always been in the air; neither has any beginning nor end.
Sages and saints all can dedicate themselves completely in the devotion to lord by embracing Om. Whoever keeps chanting Om finds his surrounding replete with positive energy. The sound Om consists of combination of three different sounds— ‘O’, ‘U’ and ‘M’— which are also considered the symbol of Brahma, Vishnu and Maheshwar respectively.
Om has been considered associated with 12 ‘Kalas’ (parts). All its ‘Matras’ carries a significant meaning. The first among the matras (metres) of 12 ‘Kalas’ is ‘Ghoshini’, the second one is ‘Vidyumatra’, and then successively comes ‘Patangi’, ‘Vayuvegini’, ‘Namdheya’, ‘Oindri’ and others.
