Reports in Tamil Media suggest that St. Joseph school in Rameswaram, Tamil Nadu, suspended two boy students for applying vibhuti (sacred ash) on their forehead.

This comes as another incidence of contempt for Hindu beliefs and customs.
These two students were studying in class 12th and were preparing for Sabarimalai pilgrimage. They came to school with the preparation garlands and vibhuti.
While on the first day they were given a warning against wearing vibhuti, but when they did it next day, the administration suspended them.

When shocked parents met the administration, it said the two students lacked discipline and were involved in unacceptable activities.

Devotees apply vibhuti traditionally as three horizontal lines across the forehead and other parts of the body to honor Lord Shiva.
Hindu symbols being banned in Christian educational institutions and Hindu students getting punished is a regular occurrence in Christian educational institutions. It is nothing but a mockery of rule of law.
Last year, St. Vincent Pallotti School in Bengaluru expelled a 3 year old LKG student because the child had a ponytail (shikha) which was part of his family’s traditions. The principal of the school, Paul D’Souza, called it as ‘superstitious practices’.

Likewise, Hindu girls in Kanpur were severely punished by St Mary’s Convent for wearing Rakhee and applying mehandi.
It is quite amazing that despite the fact that many Christian schools receive government aid, still they find it right to discriminate against Hindu students.
