Maps of Ancient Buddhist India
Anotattasaro ca Sinerupabbato ca
Mount Neru and Lake Anotatta
The Buddha is said to have traversed the great distance from Uruvelā to the Himālayas to spend the day at Lake Anotatta during the time he was trying to convert the Uruvelā Kassapa, shortly after the Awakening, but the latter was still not convinced of the Buddha's superiority. It is mentioned as one of the seven great lakes in the Himālayas.01
In the same Aṅguttara discourse Mount Sineru is mentioned as the King of Mountains (Pabbatarājā). The mountain is also known in the Pāḷi texts as Neru, Mahāmeru, Meru and Kelasa. It is identified now with Mount Kailash in western Tibet. The Lake Anotatta, which is identified with Lake Manasarovar is on the rocky plains (silātala) in front of the mountain range.
Sineru takes on mythical proportions in the Commentaries, where the Tāvatiṁsa Heaven in said to be positioned on its summit, and the abode of the Demons at its base.http://www.ancient-buddhist-texts.net/M ... Sineru.htm
