Tibetan numerology is the oldest on the planet..numbers have energy, so numerology is the energy of numbers.
Numbers have messages look at a book all the pages are numbered, & each page has a message.
Now the basic Numerology 1-9
1: New beginnings (new 1st number)
2: Duality (free choice.. decisions)
3: Catalyst ( moves..lots of healers have 3]
4: Earth..(the Earth number,Gaia, grounded)
5: change (raw change..2021=5..big changes coming)
6: Harmony: (co-operation, unity)
7: Spiritual (basis)
8: Manifestation & Abundance:. ( Not just money..long life,Health,& body healing)
9: Completion: endings, end of something).
It start to get a lot more complicated as each number has its own astrology attributes, all planets are involved.
The Master numbers are
22: strong duality
33: compassion..(number of our DNA).
The rest are pretty unknown at present.. although I am sure a aligned experienced Numerologist will have more insights on these then me…lol.
can probably give you a lot more information..if interested.
