Life segment
Your connections with another person has 4 'layers' (in a simplistic manner):
1 - physical (attraction, genetic quality, basic need to mate and procreate)
2 - emotional (being in love, having feelings, seduction, caring)
3 - psychological (valuing attributes - personality, intelligence, social status)
4 - spiritual
These layers are contained within each other like the layers of an onion. So you can have an emotional attraction that also includes physical love. However, an "inside" layer may not be included - or be misaligned - within an "outer" layer, for example, valuing someone's personality but not being "in love", or being in love with someone who is "wrong" at a social status level. Also applies to non-romantic relationships.
To have a spiritual connection means that there is a connection at layer 4. This is a spiritual layer, which you only ever come in touch with it (you only realize it) when you meet someone who makes you realize that it exists. Otherwise, you may believe it's "nonsense" or that's an invention. It isn't.
Spiritual connections are either there, or they aren't. It's a matter of family connections and bonding at spirit (metaphysical) levels. Layers 1-3 relate more to the human low-ish side of relationships, meaning in terms of raw physical attraction for biological procreation, raw emotions (which can generate drama and attachment if you govern yourself by these alone), and so forth.
This doesn't mean layers 1-3 are "wrong" or innappropriate. It means they can either be aligned with the 4th, or not. So as a human you can function at levels 1-3, or you can function mainly from the 4th one, and then work to align the others below it.
