Hayanaratna 3.124

Mercury is in Libra, in the hadda (a planet's own small part of a sign) of Saturn, an equal (neutral) planet. The Moon is in Libra at 3 degrees, in its own drekkana (one-third part of a sign). So the kambula (the Moon supporting the link of two planets) is middle-equal.

Simple meaning: Middle-equal kambula example, continued: Mercury in Libra in a neutral planet's hadda; Moon in Libra at 3 in its own drekkana.
