A group of monks came to see the Buddha and asked him for advice on meditation. The Buddha advised them with this verse and with the preceding and the following one (DhP 87, DhP 89). In order to reach the awakenment, one must abandon all cravings and "have nothing", or in other words, not cling to anything. One must also purify the mind from the "impurities", or greed, hate, delusion, conceit, speculative views, skeptical doubt, mental torpor, restlessness, shamelessness and lack of moral dread. This way, one will reach the state of arahantship and then one can truly find delight in solitude.
