Only it’s completely messed up. Why is this important? Because we’re talking about the alphabet of nature itself, the sounds that give rise to all form.
Firstly, the above symbol is Hindi, not Sanskrit. In Hindi, they adopted the simpler-to-write Sanskrit U to replace the Sanskrit A. So the above symbol is actually a stylized UUM (long U) in Sanskrit.
Here is the unstylized version.
Secondly, OM is not the Pranava mantra or primordial sound of creation becoming. That’s AUM. O and AU are 2 different letters or mantras with distinct qualities, genders, and effects. Even in English, for example, Tau and To are completely different words.
Thirdly, for a practice, both are monks mantras, not suitable for use by householders in the world. They will cause possessions and relationships to fall away from your life. The sage Shankara was responsible for a revival of the monastic transition in India. But it came to dominate Indian philosophy and overshadowed the householders path – the one the vast majority of us are on.
You often see people begin all chants and recitations with Om. This is not part of the original texts. And as you’ll note above, it’s the wrong letter anyway.
