It is not like they’re being influenced by ancestors who seek physical bodies, and are influencing their emotions towards each other.

Rishabha , Please show us some evidence where ancestors who seek physical bodies do not influence people in the subtle world to take physical bodies which can become sexually involved and in turn produce physical forms for the said ancestors or their relations.

Even though subtle people cannot have pregnancies, their sex drive may still be able to sponsor such pregnancies in time. It depends on the energy content of the sex drive of each individual involved.

It is likely that people who do not have a physical body may by the power of sex drive be induced to take another embryo for the very purpose of indulging physically with the same subtle sex drive.
