3.91

[Meru] Some say that Meru is translated here as "Luminous," referring to the seven golden mountains because they shine with golden light. Yet if one follows the Supreme Dharmavijaya Sūtra which speaks of Mount Sumeru, Meru is an older translation of Mount Sumeru. The Kośa says: 'Sumeru is also called Meru.' Thus the Sanskrit pronunciation differs. If one relies on the Lotus Sūtra which says, 'The inner and outer Meru mountains, Sumeru and the Cakravāḍa,' then their mountain bodies are also distinct.
