What it means
Amba simply means mother. It's the most familiar, homely way to address the Goddess.
Where it comes from
The aarti Jai Ambe Gauri opens with this name, and in Gujarat's garba it's the name sung most. The devotee isn't addressing a distant power here, just their own mother. Maybe that's why it comes with no method, only calling.
How to chant it
Sung with an aarti or bhajan. No mala needed.
When: Navratri, and every evening aarti.
