Having under control his body and his speech, as also his organs of sensation and his hind, he should stand with joined palms, looking at the face of his Teacher.—(192)

Medhātithi’s commentary (manubhāṣya):
On coming from some other place, ‘he should stand looking at the face of his Teacher,’—he should not sit;—‘having under control, his body’;—i.e., he should not do such acts as the throwing about of hands and feet, laughing and so forth; nor should he speak anything needlessly.

He should control his ‘organs of sensation,’—i.e, if he finds anything wonderful near the Teacher, he should not think of it again and again. He should control the Auditory and other organs also; the control of the visual organ is secured by looking at the Teacher’s face.

He should control the mind also; i.e., he should avoid the thought of difficulties pertaining to soriptural matters, or of the building of houses, granaries and the like.

The prohibition contained under 288 with regard to ‘making an effort to control, etc.,’—is meant to prohibit attachment.

The meaning of all this is that when he is near his Teacher, he should not permit the slightest movement of his organs, even towards such things as are not prohibited.

‘With joined palm’—i.e., with the hands joined together in the shape of a pigeon, turned upwards.—(192)
