Scorpio (Vrishchika) and Pisces (Meena) as Moon signs
Bhakoot
The signs are in a 5/9 relation. Bhakoot dosha (5/9), cancelled: the Moon-sign lords Mars and Jupiter are mutual friends (BPHS ch.3).
Graha Maitri
Sign lords Mars and Jupiter, read from their natural friendships.
In Ashtakoot (Guna Milan) matching, the two Moon signs alone decide two of the eight kootas that do not depend on who is the bride and who is the groom: Bhakoot and Graha Maitri. Varna and Vashya also read the Moon signs but score the bride and groom differently, and Tara, Yoni, Gana and Nadi need each Moon's nakshatra — so a full 36-point score needs both birth charts. In Vedic matching your sign is your Moon sign (rashi), which your birth chart shows. Tables: Muhurta Chintamani (Vivaha Prakarana) as given in B.V. Raman's Muhurtha; Graha Maitri from the natural friendships of BPHS ch.3.

Vrishchika
Meena
The notes below are general themes of the two signs' elements, not a reading of anyone's chart.
A full Ashtakoot score reads each Moon's nakshatra as well as its sign, and the Manglik check reads the lagna and the Moon. Enter both birth details to compute them.
