In Hebrew, each letter possesses a numerical value. Gematria is the calculation of the numerical equivalence of letters, words, or phrases, and, on that basis, gaining, insight into interrelation of different concepts and exploring the interrelationship between words and ideas.
Here is a basic introduction to Gematria that discusses different systems for identifying the numerical equivalence of individual letters, how these letters can be calculated according to the implicit word-value of their names.
The assumption behind this technique is that numerical equivalence is not coincidental. Since the world was created through God's "speech," each letter represents a different creative force. Thus, the numerical equivalence of two words reveals an internal connection between the creative potentials of each one.
here are four ways to calculate equivalence of individual letters:
Absolute Value
Ordinal Value
Reduced Value
Integral Reduced value
The Tikunei Zohar explains that the concept of reduced value is related to the spiritual world of Yetzirah. On that basis, a relationship can be established between these four forms of calculation, the four spiritual realms, and the four letters of God's name:
| letter of God's essential Name, Havayah | type of calculation | world |
| yud | absolute value | emanation (atzilut) |
| hei | ordinal value | creation (beri'ah) |
| vav | reduced value | formation (yetzirah) |
| hei | integral reduced value | action (asiyah) |
