Those who queue up to receive Amma's hugs are required to follow certain guidelines. Here are a few examples:
Wipe excess make-up and/or perspiration from your face before your darshan.
Kneel close and place your hands on Amma's chair for support (Not on Amma).
Please do not hug Amma -- let her hug you.
Amma says: To know the Self, one should starve the ego.
