OM is said to be the sound symbol of Infinite Divinity, and Brahma, Vishnu, Mahesh the trinity Deities.
To be able to reach or understand this sound symbol OM the oneness of it, all the scriptures have shown us the way.
One of the clear ways is threw the trinity Deities.
Brahma the creator deity stands for creation with his wife Saraswati the deity of knowledge and Wisdom.
“Be the Creator of your Wisdom.”
Vishnu the preserver deity with his wife Laxmi the deity of Wealth.
Mahesh the destroyer with his wife Parvati the Shakti ( strength) stands for-
” The Wisdom will give you Strength to Destroy Ego (ignorance)”
As Wayne Dyer says EGO just means Edging God Our.
In Simple words
Create (Brahma) the Wisdom(Saraswati) and Preserve (Vishnu) the Wealth (Lashmi), which will give you the Strength (Parvati) to Destroy(Mahesh) the Ego or the Ignorance.
