2. It is in the Third Eye:

In his heart dwell the Lord's Lotus Feet, and he partakes of the Divine Ambrosia.

The Lotus Feet of God come to abide within his heart, and he savors the sublime essence of the Lord’s Ambrosial Nectar.

Guru Arjan Dev –
Adi Granth, Sorath M5, p. 616

The Lord breaks the chain of doubts; and the Divine Ambrosia is tasted inside.

Break the chains of doubt, and remain unattached; you shall find the Lord, and the Lord’s sublime essence, deep within yourself.

Guru Nanak Dev –
Adi Granth, Maru M1, p. 1041
