Veneration of Avalokiteśvara Bodhisattva has continued to the present day in Sri Lanka, where he is called Nātha.[18] In more recent times, some western-educated Theravādins have attempted to identify Nātha with Maitreya Bodhisattva. However, traditions and basic iconography, including an image of Amitābha Buddha on the front of the crown, identify Nātha as Avalokiteśvara.[19] Andrew Skilton writes:[20]
... It is clear from sculptural evidence alone that the Mahāyāna was fairly widespread throughout [Sri Lanka], although the modern account of the history of Buddhism on the island presents an unbroken and pure lineage of Theravāda. (One can only assume that similar trends were transmitted to other parts of Southeast Asia with Sri Lankan ordination lineages.) Relics of an extensive cult of Avalokiteśvara can be seen in the present-day figure of Nātha.
Avalokiteśvara is popularly worshiped in Myanmar, where he is called Lokanat, and Thailand, where he is called Lokesvara

Only Maitreya Bodhisattva is accepted
Так что автор списка ошибается.
