“People usually consider thought to be something of little importance, and therefore they are very undiscerning in their acceptance of thoughts. However, everything good comes from the acceptance of correct thoughts, while everything evil comes from the acceptance of deceitful thoughts. Thought is like the helm of a ship. A small wheel and an insignificant board dragging behind a great vessel decide its direction and, more often than not, its fate”

(St Ignatius Brianchaninov assorted quotes in the book ‘Search for Truth’)
