Consequently, he left all his students except for one, Ven.Gatamanne Vimalavamsa Thera, who accompanied him in his quest for a fitting dwelling for deep meditation. The support rendered by Ven. Gatamanne Vimalavamsa Thera and Matara Sri Nanarama Mahathera in this quest, was immense. To commemorate the 2500th birthday of the Buddha Buddha Jayanti Ven. Kadawedduwe Sri Jinawansa Thera founded the Śrī Kalyāṇī Yogāśrama Saṃstha on 18 June 1951. Nimalawa Aranya Senasanaya in Kirinda was selected as the first aranya or hermitage of a number of aranya senasana which were all connected into an association named Śrī Kalyāṇī Yogāśrama Saṃstha. With the passage of time the fame of Kalyani Yogashrama grew. People in many walks of life flowed into the Aranya in search of the authentic way of meditation. But setting up the Śrī Kalyāṇī Yogāśrama Saṃstha was no easy task. Although most lay persons were attracted to Ven. Kadawedduwe Sri Jinawansa Theras extremely eloquent sermons, there were people, the lay and monks alike who resented and envied his success. But thanks to his conviction the Kalyani Yogasrama Sanstha now has over 150 Aranya with over 1500 monks. After the establishment of Sri Kalyani Yogasrama Samstha, the founder Kadawedduwe Sri Jinavamsa Mahathera was in need of finding a qualified senior bhikkhu as the Leader of the group. Then he had to invite Matara Sri Nanarama Mahathera several times and fortunately got the invitation accepted at last. Until 1992, the great meditation master Matara Sri Nanarama Mahathera was the Maha Upajjhaya (chief mentor) of the Yogāśrama Saṃstha. Currently Śrī Kalyāṇī Yogāśrama Saṃstha has expanded in Sri Lanka with notable forest hermitages like Meethirigala Nissarana Vanaya (Where the first Maha Upajjhaya Matara Nanarama Maha Thero resided in), Na Uyana Aranya, Nimalawa Aranya (the first monastery), Kurunegala Nathagane Aranya, Buttala Budu Gallena Aranya, Koggala Aranya, Minneriya Mahasen Aranya, Kudumbigala Aranya, Kurunegala Ruwangirikanda Aranya, Ampara Piyangala Aranya, Colombo Sri Kalyanadharma Ashramaya (Where the current chief mentor residing in),Anuradapura Nuwarawewa Aranya Senasanaya (අනුරාධපුර නුවරවැව ආරණ්‍ය සේනාසනය), Thalangama Sri Shanthi Yogashramaya, Padaviya Galpiyuma Aranya, etc.
