i don't tend to say who my patron deities are, i find it personal. though i do follow many Egyptian deities, along with the Horned God and Triple Goddess. as for the why, i feel a connection with them really. with the Egyptian deities, i've always been interested in Egyptology, so i incorporated them into my path when i started. my patron God and Goddess, i feel a strong connection with, i've always been interested in their mythology, their behavior, and their animal forms are of creatures i've always been interested in. the Horned God and Triple Goddess, again, i feel a connection with them. i didn't choose my god and goddess because they were cool or something, i meditated on each one, and i felt it was the right ones for me.
why do you want to know who and why people follow particular deities, or who their 'top God or/and Goddess' is like it's a reality show or something?
