Standing to one side, the godling Subrahmā addressed the Buddha in verse:

“This mind is always anxious, this mind is always stressed about stresses that haven’t arisen and those that have. If there is a state free of anxiety, please answer my question.”

“Not without understanding and fervor, not without restraining the sense faculties, not without letting go of everything, do I see safety for living creatures.”

That is what the Buddha said. … The godling vanished right there.
