Sikhism - The Sikh Ceremonies
The Naming Ceremony
The Sikh naming or christening ceremony is well established and it takes place in a Gurdwara8 in the presence of relatives and friends. The family offers donations, Karah Parshad and a Rumala which is a covering for Guru Granth Sahib, made of high quality silk, cotton or embroidered cloth. Prayers are offered asking for a special blessing of good health, long life and the Sikh way of life, Gursikhi for the child.
After reciting Ardas, Guru Granth Sahib is opened at random. The first letter of the first word of the hymn on the page is selected as the first letter of the child's name. The given name is common for either sex. The word Kaur meaning 'princess' is added after a girl's name, and the name Singh meaning 'lion' after a boy's. For example, if the first letter is "P", the male child may be given a name like Partap Singh, Pritam Singh or Puran Singh or any other such name beginning with the letter "P". If the newly-born is a girl the name would like wise be, Partap Kaur, Pritam Kaur or Puran Kaur.
