From the NIV, 1 Samuel 28:3b claims "Saul had expelled the mediums and spiritists from the land." clearly implies that Mediums did reside in the land. Being Saul was at war, verse 6 shows he had exhausted all options he had except seeking out a Medium "He inquired of the Lord, but the Lord did not answer him by dreams or Urim or prophets." And in the next verse, he did seek out the medium.
Happiness is the result of an enlightened mind whereas suffering is caused by a distorted mind.
