For general enquirers and volunteering:
There are no specific requirements for visiting and taking part in the various activities of the centres of the Ramakrishna Order. Many people volunteer their time and energy to aid the various service-oriented activities of the organization. The daily evening Arati and devotional singing is a part of most of the centres. Many centres also have a definite schedule of weekly/monthly discourses, spiritual-meets (Bhakta Sammelan), annual celebrations, seminars, retreats etc. You may seek out the head of the particular centre for spiritual counsel.
If especially interested in volunteering for some of the activities of the Math/Mission, you are encouraged to regularly visit the centre and get to know the monastics and other senior volunteers/devotees.
