觀無量壽佛經疏 2.50

2.50

Answer: 'Anything private and secret cannot be practiced for long; even if cleverly and securely hidden, the matter will still be exposed. The father-king being imprisoned inside the palace, the queen consort came and went day after day; if she did not secretly carry roasted flour food, there would be no way for the king's life to be preserved. When it is now said to be "secret," this speaks of the queen consort's intention from the perspective of the gatekeeper. The queen consort thought it was secret and outsiders did not know, not anticipating that the gatekeeper was completely aware of it. Now that the matter was exhausted and there was no way to hide it from each other, he therefore told the king everything in full.'
