Tarabala “0” (janma) is always reciprocal to itself (if A is janma to B, then B is janma to A)

Tarabala “1” (sampada) is always reciprocal to “8” (atimitra) – A enriches B, so B feels love for A

Tarabala “2” (vipada) is always reciprocal to “7” (mitra) – A drains itself for B, so B feels friendly to A.

Tarabala “3” (kṣema) is always reciprocal to “6” (naidhana) – A protects B, so B is a liability for A

Tarabala “4” (pratyak) is always reciprocal to “5” (sādhana) – A attacks B, so B grows stronger from A.

You should be able to see the larger groups now.

3 and 4 (kṣema and pratyak) are a group – because they are basically the same dynamic: Protecting or Attacking. The result is weakening (6) or strengthening (5), respectively.

1 and 2 (sampada and vipada) are a group: enriching or depleting. The result is love (8) and friendship (7), respectively.

In most of the pairs one party prospers at the others expense. But in two of the 5 pairs, both parties have the same outcome. These are the 1-8 and 0-0 pairs.

In the 1-8 pair, atimitra (love) benefits the giver, and the giver (sampada) benefits the beloved.

The 0-0 pair I have not finished understanding yet. I have not decided if it is mutually beneficial or mutually problematic or mutually neutral. It is situation where two entities become inseparably intertwined and the prosperity or failure of one is identical to the prosperity or failure of the other.
