The Moon in Jyeshtha
Jyeshtha is entirely inside Scorpio, the sign where the Moon is debilitated. Its deity is Indra and its Vimshottari lord is Mercury. A Moon in Jyeshtha is a fallen Moon by sign and a Mercury-ruled star, so the birth dasha is Mercury's.

Fall and a star, together
Debilitation is the sign, not the star. Anuradha, also in Scorpio, is a fallen Moon too, but its dasha lord is Saturn. Jyeshtha's lord is Mercury, so the childhood clock is different. Mercury's full mahadasha is 17 years, and only the unspent part of Jyeshtha remains at birth. If the Moon is late in the star, the balance is short and Ketu's 7 years follow, because Ketu comes after Mercury in the order. The mind is in a water sign of Mars, fixed, with an Indra deity of primacy and a Mercury timer. That stack is the effect. A single word like secretive misses the timer.
House from the lagna
Scorpio's house depends on the rising sign. For Aries, the Moon in Jyeshtha is in the 8th, a debilitated mind in the longevity and crisis house, a heavy placement. For Gemini, Scorpio is the 6th, so the fallen Moon sits in conflict and service. For Libra, Scorpio is the 2nd, so it sits in family money and speech. The star does not change. The department does. Mars, as Scorpio's lord, disposits this Moon. A weak Mars makes the host of a fallen Moon weaker. A Mars in its own sign or Capricorn gives the host some strength the Moon itself lacks.
Mercury's years, and Sade Sati
During the Mercury balance and any later Mercury mahadasha, this Moon's topics are easier to see: speech under emotional pressure, analysis used as control, a mind that wants the last word, which fits Indra's eldest-star image without turning it into a fate. Sade Sati for this person is Saturn through Libra, Scorpio, and Sagittarius, because it is counted from the Moon's sign. The middle phase is Saturn in Scorpio, on this Moon. That transit is heavier on a debilitated Moon than on a Moon in Taurus. It is still a transit, not a second debilitation.
