Medhātithi’s commentary (manubhāṣya):
‘Tiraskṛtya’—‘placing between’—the stick, etc.; on that he shall pass urine. Or, ‘tiraskṛtya’ may mean ‘having covered;’ in which case, the meaning would be that ‘he should cover the ground with sticks and then pass urine.’ In this latter case, the reading with the lnsturmental-ending—‘tṛṇādinā—would be clearer; the construction being—‘having covered with sticks or with clods, or with leaves, or with grass.’

‘Pass it’—i.e., pass urine and evacuate his bowels.

‘Restraining his speech, clean’—i.e., with mouth not unwashed (not having anything in his mouth).

‘Body wrapped’—covered with cloth.

‘Covered’—the head tied up. The rule prescribed is—‘with the sacred thread on his ear, etc.’—(50).
