Number Compatibility: Friends, Neutrals & Enemies
Why do some numbers click and others clash? It comes straight from the friendships of their ruling planets. Learn the pattern and you can read compatibility for any pair.
In Part 2 you learned that every number is ruled by a planet. Number compatibility follows planetary friendship: if the planets behind two numbers are friends, the numbers harmonise; if the planets are hostile, the numbers create friction. This single principle lets you read the compatibility of any two numbers — for relationships, partners, or even a phone or house number.
The friendship pattern
Using the classical planetary friendships, here is a practical guide to how each number relates to the others:
| No. | Planet | Friendly with | Difficult with |
|---|---|---|---|
| 1 | Sun | 1, 2, 3, 9 | 8 |
| 2 | Moon | 1, 2, 3, 5 | 8, 9 |
| 3 | Jupiter | 1, 2, 3, 9 | 6 |
| 4 | Rahu | 5, 6, 8 | 1, 2, 9 |
| 5 | Mercury | 1, 4, 5, 6 | — (mixes easily) |
| 6 | Venus | 4, 5, 6, 8 | 1, 2 |
| 7 | Ketu | 5, 6, 7 | 1, 2 |
| 8 | Saturn | 4, 5, 6, 8 | 1, 2, 9 |
| 9 | Mars | 1, 3, 9 | 4, 8 |
These are general tendencies from the planetary friendships; different traditions vary slightly. Use them as a guide, and always weigh the whole picture.
How to read a pair
1. Find both Driver numbers (Mulank) from Part 1.
2. Check the grid above — are the two numbers friendly, neutral or difficult?
3. For depth, also compare Destiny numbers (Bhagyank) for long-term direction.
For example, a 1 (Sun) and a 3 (Jupiter) share warm, friendly planets — an easy, supportive match. A 1 (Sun) and an 8 (Saturn) mix two strong but opposite forces — powerful, yet needing patience and respect.
