Chasidut על אבות 3:6

This verse applies to all congregations, whenever Jews gather, in all times. As the Sages said, (Pirkei_Avot.3.6) "When ten sit together and occupy themselves with Torah, the Shechinah abides among them."

Similarly, within the individual person, when he gathers all his powers to submit willingly to God, he is included under 'all of your congregation.' Thus we find (Pirkei_Avot.3.6) "And how do we know that even if one [sits and studies, the Shechinah is present]."
