3. It is in the Tenth Door (Daswan Dwar):

When the soul is withdrawn from the nine doors and enters the tenth door – Dashwan Dwar – behind the eyes, it tastes the Ambrosia.

Beauteous is the township of the body¹, in which one buys the Divine Ambrosia of the Lord's Naam.

Kalyan M4, 1323-14

The body has nine doors, insipid are their tastes; and it is in the Tenth that drops the Nectar. Oh God, be merciful that we may drink, the Divine Ambrosia through the Guru's Word.

Kalyan M4, 1323-13
