Context

“Conscience is the chief of conservatives. “Perform the settled functions,” says Kreeshna in the Bhagvat-Geeta; “action is preferable to inaction. The journey of thy mortal frame may not succeed from inaction.”—“A man’s own calling with all its faults, ought not to be forsaken. Every undertaking is involved in its faults as the fire in its smoke.”—“The man who is acquainted with the whole, should not drive those from their works who are slow of comprehension, and less experienced than himself.”—” source
