All of the Planets have general significations representing people or things. The condition and placement of the Planet by Sign/House will tell you what.
Venus in good condition signifies love, beauty, harmony and artistic endeavors. Venus in bad condition is lust, wantonness, promiscuity and excess.
Modern astrologers will tell you Neptune indicates substance abuse, especially Sun square Neptune, but I have 163 charts of alcoholics and only 5 have Sun square Neptune and out of those 5 charts, you might be able to coerce two of them into suggesting substance abuse because the Sun happens to be in the 1st House. The real culprit is a badly placed or badly aspected Venus that indicates substance abuse.
Jupiter is always the general significator of wealth, and also religion, clergy, professional educators etc. In bad condition he can signify piously hypocritical people, over-indulgence, over-expansion and such.
When you have a Collection of Light, the Collector will tell you who or what makes it happen, depending on is location East or West of the Sun (Oriental/Occidental) and its position in the chart. So it could be your mother, a friend, a co-worker, or a thing like a marriage, death, your jobs, a concert, a banquet or something.
You can use Lily's definitions for the signification of Planets, since he copies Bonatti who copies al-Qabasi who copies Rhetorius.
