Your "passions" are the things you care about most intensely and towards which you dedicate much of your time. Those "things" can be anything. They could be food, music, basketball, or literature. The word "passion" is used frequently to refer to sexual passion, but you can use it for anything. Do not use the word lightly because a passion is something very intense. Generally, you should have a small number of passions, and maybe just one or none at all. Saying that you "have a passion for baseball" is a stronger statement than saying you "love baseball". If you use the word to describe too many things, people will think that you are not sincere.

You do enjoy deconstructing the deeper meaning within language. Good form! Perhaps passion is a way of saying: del be del râh dâreh. Where hearts join together. These are places of the heart and soul. Passion is the outcome of such a deep connection.

In the context provided, the word "passions" likely refers to the intense and strong emotions, interests, or desires that the person being addressed (the one from whom everything came) has. The statement suggests that not only did various things come from that person to the speaker, but even their passions or deeply felt emotions became a part of the speaker's own experience or identity. The metaphor of a soul creeping into another like a worm into an apple conveys a sense of intimate and profound connection.
