Indeed, guilt does feature substantially in the stories people tell themselves are true.
And then there is fear. People often believe the opposite of "love" is "hate," but in observing people in action and interaction, it often holds true that the opposite of love is actually fear. And guilt is one of the many things that derive from fear: When we look within, and stand in our truth with authenticity and no fear, such things a guilt, shame, judgment, envy and others tend to just fall away.
Bright Blessings!
Indeed, fear is projecting guilt into the future. As long as there is believe in guilt and time, there will always be fear too. <3
