Episode 21 -- Come Be My Light ch 3.5 -- He Forbade Me Even to Think about It

What was the reaction of Mother's spiritual director to her disclosing what happened to her in Darjeeling?

Ignore it. Fr Van Exem first tried to tell Mother Teresa not to think about what she had heard from Christ. He wanted to test her obedience. He wanted her to be silent and pray. She had many things to do in her current vocation. If this vision was really from God, Mother would be obedient.
