Your teachers teach you secular sciences in the class room, but spiritual learning is more important than secular learning. Spiritual education is like an ocean and the secular sciences like physics, chemistry, and botany, zoology etc. are the rivers. The rivers of secular learning should merge into the ocean of spiritual learning. This brings about unity in diversity. This Unity in Diversity is seen right in front of us.
Beings are many but breath is one.
Hence resolve to sanctify your hearts in the Summer Classes by contemplating on God.
