Tilak

In Hinduism, the tilaka, colloquially known as a tika, is a mark usually adorning the forehead at the point of the ajna chakra and sometimes other parts of the body such as the neck, hand, chest, or the arm. The tilaka may be applied daily for decorative purposes, as a symbol of religious affiliation, for rites of passage, or other special spiritual and religious occasions, dependent on regional custom. It is also used to honour and welcome someone upon arrival.
