Like-engirdling

Positive aspectual relationship between signs ruled by the same planet, ie Virgo & Gemini, both ruled by Mercury; Libra & Taurus, ruled by Venus; Scorpio & Aries, ruled by Mars; Capricorn & Aquarius, ruled by Saturn. Leo & Cancer fit into this schema and are considered to have the same ruler, even though ruled respectively by the Sun and Moon. In addition to the geometric equilibirum, possibly this idea came through the two being both Luminaries.

Lilith

The "Black Moon", a supposed invisible satellite of the Earth, also an energy vortex in the Sun-Moon-Earth system. There is as well an asteroid called Lilith. Lilith, the Dark Goddess, is a Hebrew name for Caput Algol, the Demon Star. In mythology, Lilith was the first wife of Adam, formed like him from the earth, rather than from his rib, like Eve.

Lunar Mansions

27 traditional sectors (nakshatras) of the zodiac, where the Moon spends her time on a day by day basis. Each mansion, of 13° 20' duration, has a specific influence, especially if Moon, Sun, Ascendant, or Ruling Planet are placed there. This system is mainly used today in Indian (Vedic) astrology. There are also ancient Chinese, Arabic and Renaissance systems, using 28 lunar mansions of 12° 51' 26" of arc.

Lunar Month

See Lunation.

Lunar Node

See Nodes

Lunar Return

Time of the month when the transiting Moon is conjunct natal Moon.

Lunar Return (Progressed)

A very significant time in life when the progressed Moon reaches the conjunction with natal Moon for the first time at around age 27, marking the first part of the difficult transition from the phase of Youth to the phase of Maturity associated with the Saturn Return. The second Lunar Return occurs around age 54 and the third around age 81. See Saturn Return.

Lunar Standstill

Approximately every eighteen and a half years, the Moon reaches a major turning point, analogous to the Solar Solstices. The interval between Full Moons rising is called a month. A significant longer cycle lasts 18.61 years. The most northerly of the monthly moonrises allow the 18.61 year standstill cycle to be perceived by naked eye astronomers. Over 9.3 years these northerly moonrises shift from rising south of the summer solstice sunrise location to north of the summer solstice sunrise location. Each end of this 18.61 year journey is called a Lunar Standstill. It is considered extremely powerful and is marked by many ancient stone circles.

Lunation

A lunar period, measured from one place in the zodiac until the Moon's return thereto, usually referring to the period from one New Moon to the next (averaging 29 days, 12 hours, 44 minutes). The time taken by the Moon from one conjunction with the Sun until the next, 29 days, 12 hours, 44 minutes and 3 seconds, is called a Synodical Lunation. Lunation is also loosely used to describe different aspects of the Moon to the Sun, thus accounting for her phases. The New Moon is also often called a Lunation and a chart made for the moment the Moon conjoins the Sun is called a Lunation Chart.
