Medhātithi’s commentary (manubhāṣya):
‘Non-existence’ may mean either death, or absence of proper qualification.

‘When all these are non-existent,’ he should carry on the tending of the fire,—i.e., he should continue to wash and besmear with clay the fire-house, he should kindle the fire, he should constantly keep near the Fire, just as his Preceptor used to do;—all this constitutes the ‘tending of the fire.’ While doing all this, ‘he should perfect his body’—i.e., let it wear away; this is called ‘perfecting’ in the same manner (of contrary signification) as the blind man is described as ‘having excellent eyes.’

‘Sthānāsanavihāravān’—‘with only such diversion as standing and sitting’; i.e., he should amuse himself only by standing for sometime and sitting for sometime.

Others have explained this to mean that he ‘should sit in the proper posture for meditation’—such as the Svasti(k/h?) and the rest—‘and should go about begging alms.’—(248)
