What is the resort of Nibbaana?

In Unnabho Brahmano Sutta: The Brahman Unnabha says > "There are, Brahman, these five sense-faculties... which do not share > in each other's sphere of action. Mind is their resort, and it is mind > that profits from their combined activity." > > "But, good Gotama, what is mind's resort?" > > "Mind's resort, Brahman, is mindfulness." > > "Then, good Gotama, what is the resort of mindfulness?" > > "The resort of mindfulness, Brahman, is liberation." > > "Then, good Gotama, what is the resort of liberation?" > > "The resort of liberation is Nibbaana." > > "Then, good Gotama, what is the resort of Nibbaana?" > > "That question goes too far Brahman. No answer can encompass it. The > aim of the holy life, Brahman, is immersion in Nibbaana, it has > Nibbaana for its final end, Nibbaana for its conclusion." Is this suttha says Nibbaana resort on five seance faculties? or If Not how can it seance?
