"That's why India is called the spiritual school of the planet and Tibet its sanctuary,"

The exact phrasing, "That's why India is called the spiritual school of the planet and Tibet its sanctuary," is a philosophical and esoteric concept often discussed in spiritual communities and theosophical traditions. 

While it doesn't trace back to a single universally credited historical figure, it perfectly mirrors the celebrated words of the 14th Dalai Lama. He famously uses similar language to describe the relationship between the two regions, referring to India as the spiritual home or "guru" and Tibet as the dedicated student ("chela") that preserved India's ancient wisdom.
