I'm uncertain which number you're referring to as being your spiritual number. However, your numerology chart destiny number (the primary name number) is highly spiritual.

It's the number 7. The energy 7 represents isn't only spiritual, it is also (among other things) intuitive, introspective, and tends to thoroughly analyze things before accepting them as facts.

Your numerology chart has the number 7 in five significant positions:

1. Your destiny (as mentioned earlier).

2. Your heart's desire.
3. Your cornerstone.
4. Your life path.
5. Your current (and previous) pinnacle cycle.

The first three on the list are determined by your name. The last two by your birthdate.

The destiny number is often referred to as the name number and the life path number as the birthdate number. Those two are the most significant of all numerology chart positions.
