I saw a post on Social Media today about Robotic Affirmations.
Like any technique, they're almost a total waste of time. Then again, you've got time.
My answer, which I love, was that:
"The only thing that manifests is Imagination. However else you think you're doing it, is absolutely fine."
Manifestation works because our world is comprised of a single "substance," that is Spirit. This is The First Principle.
Imagination manipulates Spirit.
While this is reductive, it can only really be understood by lived experience, but understanding it is key.
Whatever you do to create in Imagination is fine, but let's not mistake "techniques" for Cause. You are the Cause. The One Cause.
