Sallekhasutta

mn8:10.1 It’s possible that some mendicant, going totally beyond the dimension of infinite consciousness, aware that ‘there is nothing at all’, might enter and remain in the dimension of nothingness.

mn8:10.2 They might think

mn8:10.3 they’re practicing self-effacement.

mn8:10.4 But in the training of the Noble One these are not called ‘self-effacement’;

mn8:10.5 they’re called ‘peaceful meditations’.
