注大乘入楞伽經 1.193

1.193

魔羅，此云能害。凡障善品，能害慧命，皆名為魔。總有四種：謂煩惱魔、死魔、陰魔、天魔。此問：諸魔及異學者，欲修行人識生死諸見根本也。

Māra translates here as "one capable of harming." Anything that obstructs wholesome factors and can destroy the life of wisdom is called a mara. In general, there are four kinds: the defilement mara (kleśa-māra), the death mara (mṛtyu-māra), the aggregates mara (skandha-māra), and the deva mara (devaputra-māra). This question about the maras and non-Buddhists intends for practitioners to recognise the roots of the various views within saṃsāra.
