To see no error is a state of mind you can only be in through joining with the Holy Spirit. Human beings are not capable of seeing without error. The five senses were made to always notice error. So we need to sink deep into our minds in order to experience this state.
Any darkness in the mind does need to be released. Once this purification has occurred all the love and gratitude in our hearts will naturally begin to pour out.

Here is another fun parable from David's early days of traveling. The joy is really in following the Guidance even if it seems absurd!
