Dhyan Ashram Retreat House was started in 1975.  Three two-story blocks were built in the large campus and were named Anjali, Bairagi and Chinmayi.  Anjali block was used to house the retreatants while the other two housed the novitiate which was started the same year.  All these buildings are gone now.  At the location of Anjali, a new and bigger retreat house was built in 2010 and was named Jayanti (in memorial of the 150th year celebration of the arrival of Belgian Jesuits).  Earlier a chapel cum auditorium block was built and named Milanmela.​
