Śrī Kalyāṇī Yogāśrama Saṁsthā, also known as the Galduwa Forest Tradition is an independent part of the Sri Lankan Amarapura–Rāmañña Nikāya Buddhist ordination line, with their headquarters in Galduva, Kahawa, Ambalangoda. They keep a strict standard of Vinaya, recognised as the strictest standard of any major organisation in Sri Lanka. It is the largest forest sect of the Sri Lankan Sangha. Their monks are easily recognised by the palm-leaf umbrella they use and by the habit of wearing the Sanghati whenever they walk outside the monastery boundaries. Remarkably for Sri Lanka, all castes are accepted for ordination. Foreign monks, who wish to become resident at one of their monasteries, are usually expected to undergo the so-called "Dalhi-Kamma" at Galduva, a short ceremony meant to reconfirm the validity of their original Upasampada according to Galduva standard. After that they are accepted according to their normal seniority.
