People can most certainly be beacons. It has to do with what we radiate, we are all made up out of magnetic pulse, we pulsate energy. Depending on how we feel this energy can be different for everyone. Some people have a natural higher or more rapid frequency which makes them natural healers or psychics or what have you.
I don't know if you attract them on a spiritual level though, it might just be that you share a lot of the same interest and that they find that in you.
"If you take a copy of the Christian Bible and put it out in the wind and the rain,
soon the paper on which the words are printed will disintegrate and the words will be gone.
Our bible IS the wind and the rain."
