Jhāna Sutta (AN 6:73)
“Monks, without abandoning six things, one is incapable of entering & remaining in the first jhāna. Which six? Sensual desire, ill will, sloth & drowsiness, restlessness & anxiety, uncertainty, and one has not seen well, with right discernment—as they have come to be—the drawbacks of sensuality.1 Without abandoning these six things, one is incapable of entering & remaining in the first jhāna.”
