According to Ra, ambrosia is the food of 4th density

[AnthroHeart]

I've read, specifically on the AYP forums, of people who have a spiritual practice, and sometimes they'll find a sweet, sort of liquidy goo drip down the back of their throat during meditation. This is how I've always perceived "ambrosia."

I know the kechari mudra is practiced in part to access this "nectar" too.....

That's awesome. I've definitely had that but didn't know what it was. Never really tasted it, but could feel it definitely.
Inside my mouth is my strongest manifestor.
