Bhīṣma said: One should ensure that dogs and Brahmins who spoil the funeral-feast line do not in any way cast their gaze upon the śrāddha. Therefore, the offering should be made in a well-enclosed place, and sesame seeds should be scattered around to ward them off and protect the rite from defilement.
भीष्म उवाच
Śrāddha should be protected from ritual defilement: the performer must prevent improper onlookers or disruptive/impure participants from affecting the rite, and should take practical measures (enclosure, scattering sesame) to safeguard its sanctity.
In Bhīṣma’s instruction on dharma, he gives a procedural rule for conducting śrāddha: perform the offering in a secluded/enclosed spot so that dogs and ‘line-spoilers’ do not see it, and scatter sesame seeds around as a protective measure.
