Question: What is that white marking on the foreheads of ISKCON devotees?
Answer: That is called ‘tilak’ (“tee-luck”).
It is clay taken from holy places and used to adorn the body of a devotee.
Just as you recognise a temple as a special place of worship by its markings, similarly the devotee marks his or her body with tilak to indicate that the body is a temple of God to be used in God’s service.
It also indicates that the person’s head is always bowed in a position of submission before God.
