A few quotes from the Rabbi on 'Torah Study'
in which he teaches that the kedusha ritual was instituted so that the People of Israel would all be involved in Torah
The kedusha prayer reads from the verse, "But You are the Holy One, enthroned, the Praise of Israel" to "and make their hearts constant toward You". It was instituted so that all People of Israel would be involved in a minimal amount of Torah every day, meaning that reading and explaining are equivalent to involvement. And since it is customarily said throughout the people of Israel, both scholars and simple folk, its value is twofold: sanctification of the Name and Torah study.
