Sharing one or more of the following six cross aspects with another person may potentially foster inexplicable FEELINGS of fatedness, kinship, and deep connection between the two people involved. 1. Let Me Lose Myself in You! (or Calgon, Take Me Away...) Cross aspects between person A's birth Neptune and person B's birth luminaries and personal planets (Sun, Moon, Mercury, Venus and Mars)... The conjunction, trine and sextile aspects are (for the most part) a bit "easier" to handle - with the conjunction being the most intense connection. Cross aspects involving Neptune and the other person's luminaries and personal planets can even hold true with sign conjunctions and oppositions that aren't necessarily within orb aspect - but generally speaking: the closer, the better. Finding what's sometimes called a "double whammy" cross aspect - such as person A's Neptune conjunct person B's Venus and person B's Neptune sextile person A's Venus - is all the better for creating that special connection feeling. A double whammy helps create mutuality of feeling (with both people feeling the same way about each other).
2. Haven't We Met Somewhere, Before? (You're so familiar) Look for person A's birth planets conjuncting the angles of person B's chart (Ascendant/ Descendant axis or the Midheaven/ I.C. axis). This is especially true of person A's luminaries and personal planets (Sun, Moon, Mercury, Venus and Mars) and especially true of conjuncting person B's Ascendant/Descendant axis.
Again, if you find a double whammy - such as person A's Ascendant conjunct person B's Moon and person B's Ascendant conjunct person A's Moon - then all the better! 3. We May Never Pass This Way Again (Karmic Lovers) Cross aspects between the Sun, Moon, Venus and/or Angles (Ascendant/ Descendant axis or the Midheaven/ I.C. axis) in person A's chart and person B's Lunar Nodes. The conjunction is the most intense (and compulsive) and gives the strongest "feeling" that the two of you have been together in previous incarnations. The conjunction, trine, and sextile aspects are (for the most part) a bit "easier" to handle than squares and oppositions. Again, look for a double whammy.
4. You Are My Destiny (Destiny's Gate) Cross aspects between the Sun, Moon, Venus and/or Ascendant in person A's chart and person B's birth Vertex.
This is especially true with conjunctions. I personally don't concern myself much with looking for the other aspects. (Sometimes, I break my own rule and look for other aspects.) Again, look for a double whammy.
5. Hey, Venus! (Love in the Afternoon) Cross aspects between the Sun and/or Moon in person A's chart and person B's birth Venus. This is especially intense with conjunctions, squares, and oppositions, but trines and sextiles are awfully comfortable and nice. Again, look for a double whammy.
6. Immortal Lovers (Ooh baby, ooh baby...) Now here's one you probably haven't heard of before... I originally got clued into this connection by astrologer Kira Ivory, although I'm not exactly sure how she uses them. The Immortal Lovers concerns the minor asteroids named Eros and Psyche. If this is a relationship between a male and female - then first look for the male's birth Eros conjuncting the female's birth Psyche. This even appears to work with sign conjunctions which aren't in orb. In my experience, finding this cross aspect between lovers is fairly rare... (If this is a relationship between same-sex partners, then first look for the more masculine partner's birth Eros conjuncting the more feminine partner's birth Psyche.) Bringing it down a notch, this also seems to work fairly well with (in orb) aspect oppositions and squares. Then, to a much lesser degree, it can work with trines and sextiles. (Although, as a general rule I don't consider trines and sextiles when comparing Eros and Psyche.) Then... check to see if anything's up between the female's birth Eros and male's birth Psyche. Finding a double whammy cross aspect between lovers (involving conjunctions, oppositions and squares) is rare... Note: Finding a double whammy between family members seems to be rather common (which is sort of a scary thought, but consistent with many of the differing theories on reincarnation).
