佛說觀佛三昧海經 6.18

6.18

The Buddha told his father, the king: 'Even if someone were to mature beings with wrong views, in number as stated above, and cause all those persons to attain the path of the arhat, with the three knowledges, the six supernormal powers, and endowed with the eight liberations, it would still not equal generating the mind that aspires to the Buddha's wisdom and being mindful of the Buddha for a single moment.'
