Saha nāvavatu, may the Lord protect us both

Saha nāvavatu, may the Lord protect us both. What is meant by protecting with reference to the study? When the teacher is unfolding something, he is trying to communicate, and the student is making an attempt to listen and understand. When this process of communication takes place, it is necessary that our mind should be free from other distractions.
