Those as practitioners of the path, are like bulls carrying heavy burdens, walking in deep mud within, even if extremely weary, not daring to look about to the left and right, only when departed from the mud, then can they rest. Śramaṇas should contemplate passionate desires, to be more [dangerous than] mud. With the straightforward mind mindful of the path, then can they be spared from suffering.
— Śākyamuni Buddha
