The Sanctum is the holy of holies at the Golden Temple. It is made of marble and plated with real gold. It’s the place where the holy book is read/chanted. The reading is lyrical engaging the soul unlike a dry recitation of words. Though I understood not a word, I was carried along by the rhythm of the chant. The water around the Sanctum is called the pool of nectar. I like the implication that the pool is sustenance for the soul. Unfortunately, photos are forbidden in the Sanctum so all I have of the interior is fading memories to recall the experience.
