Are you familiar with the concept of long-term memory?

When we are familiar with something our brains re-wire themselves with a specific pattern of neural connections and impulses, which when fired trigger a memory.

These memories are often related to specific plcace, items, or people. When someone we love dies, they are often so deeply ingrained in our memories that we will never forget them (barring traumatic brain injury).

This is most likely what is meant by the song. The singer will never forget the path the person they are talking about showed them, and they will always remember the guidance received.

There's nothing metaphysical, no soul fragments or anything like that. Just plain old boring human memory.
