BṚHADĀRAṆYAKA UPANISHAD · 6.1.5

यो ह वा आयतनं वेदायतनं स्वानां भवत्य् आयतनं जनानाम् ।
मनो वा आयतनम् ।
आयतनं स्वानां भवत्य् आयतनं जनानाम् ।
य एवं वेद ॥

yo ha vā āyatanaṃ vedāyatanaṃ svānāṃ bhavaty āyatanaṃ janānām ।
mano vā āyatanam ।
āyatanaṃ svānāṃ bhavaty āyatanaṃ janānām ।
ya evaṃ veda ॥

He who knows the home, becomes a home of his own people, a home of all men. The mind indeed is the home. He who knows this, becomes a home of his own people and a home of all men.
