It is interesting how one word can entirely change the meaning of a phrase. In today’s fortune, we would expect it to say “You are always welcome at gatherings.”
Being welcome at something implies being on the receiving end of an invitation. Someone else has initiated the gathering and you are welcome to attend.
Instead, it says to.
Being welcome to something is a more proactive position. It puts the power within you to initiate an event or an action. You are the master of your fate. You are the captain of your soul. Like Seth Godin continually says, stop waiting to be picked. Choose yourself.
To your good fortune!
