Ramakrishna Mission’s Sunday Religious school is the oldest of its kind started in 1952 and has celebrated its Golden Jubilee in 2002. The main task of the school is to harvest the inner potentials of students and to develop their character. ‘We are the makers of our own destiny’, Swami Vivekananda says. Accordingly, the Sunday religious school facilitates each student to build their own future on their own will and provide them with all personality development skills. The success of this ideal has been later adopted and many Sunday religious schools were initiated by the Government of Sri Lanka in all parts of the country in late 1990s.

There are more than 800 students studying in the Colombo centre Sunday religious school and more than 100 in the Baticaloa centre. The religious school starts at 8:45 AM on every Sunday and finishes at 11:30 AM. Every minute spent in the school will be a progress toward the character development.

• Students are required to place their chapels and shoes properly into their allocated space. Importance to discipline is given even in keeping the chapels properly, because every small action contributes to a larger character development.
• Each class takes turn in cleaning the class rooms and the surroundings every week. By doing this, students are made aware of the cleanliness and an ownership the place.
• Every week there will be notice board that displays a quote of the week from sayings from great prophets. Students are expected to remember and practice these during the week.
• Preparing garlands and preparing for pooja is done by the students themselves. Purity is strictly observed during this practise.
• Students gather in the prayer hall and participate in the pooja, chanting and bhajans. The Swami-in-charge of the religious school directly conducts this prayer and pays attention to every student. Finally the prayer ends with a few minutes silence and meditation.
• Then the students are grouped in to classes where each class will have 10 to 20 students and will have a teacher.
• The students are taught with music, the great ideals, histories of great religious leaders and other personality development aspects.
• Finally each student is given with Prasad and sent home with a very happy and spiritually nourishing thought.
• Teachers and volunteers assembled together and given guidance directly by the Swami-in-charge of the religious school.
• The school celebrates important religious events such as Holy Trio’s Jeyanthy, Krishna Jeyanthy, Vinayaka Chaturthy, Chirstmas, Vesak, Navaratri and other important events. Students themselves decorate the halls and perform dramas, dance and other cultural activities under the guidance of teachers and Swamis.
• Two magazines are released by the students of the school. A yearly hand-written magazine ‘Viveka Vahini’ and another printed quarterly magazine ‘Araneri Amudam’ selling about 3000 copies on every release.
