ननु कथम् एको देवः, जीवपरयोर्भेदात् ? न ; 'तत्सृष्ट्वातदेवानुप्राविशत्' 'स एष इह प्रविष्ट आ नखाग्रेभ्यः' इत्या-दिश्रुतिभ्योऽविकृतस्य परस्य बुद्धितद्वृत्तिसाक्षित्वेन प्रवेशश्र-वणादभेदः ॥प्रविष्टानामितरेतरभेदात् परात्मैकत्वं कथमिति चेत्, न;'एको देवो बहुधा संनिविष्टः' 'एकः सन्बहुधा विचारः''त्वमेकोऽसि बहूननुप्रविष्टः' इत्येकस्यैव बहुधा प्रवेशश्रव-णात् प्रविष्टानां परस्य च न भेदः ।'हिरण्यगर्भः' इत्यष्टौमन्त्रा: 'कस्मै देवाय' इत्यत्र एकारलोपेन एकदेवत्वप्रतिपा-दका: तैत्तिरीयके ।
In plain words
Objection: How can God be one when the individual soul and the Supreme appear distinct? Not so; because texts like 'Having created that, He entered right into it' and 'He has entered here down to the very tips of the nails' declare that the unchanging Supreme enters simply as the witness of the mind and its movements; therefore, they are non-different. If you ask: Since the entering souls differ from one another, how can there be oneness with the supreme self? We reply: There is no contradiction, for scripture states that the one God has entered in manifold ways—'The one God is placed in many forms,' 'Being one, He appears as many,' 'You alone have entered into the many.' Because the single Supreme is thus declared to enter in manifold ways, the entering souls and the Supreme are not different. In the Taittiriya recension, the eight mantras beginning with 'Hiranyagarbha' and the hymn 'To which deity' establish this singular divinity through the elision of the vowel 'e'.

Objection: How is God one, given the difference between the individual soul and the supreme? No; because scriptural passages like 'Having created that, He entered into it indeed', 'This one having entered here up to the nail-tips', declare that the unchanged Supreme enters as the witness of the intellect and its modifications, hence there is non-difference. If it be asked: How can there be oneness of the supreme self when entering entities have mutual differences? No; because Vedic texts declare that the one God entered in manifold ways: 'The one God is manifoldly situated', 'Being one, He manifests variously', 'You alone have entered into many', showing that the single Supreme enters in manifold ways, hence there is no difference between the entering souls and the Supreme. In the Taittiriya, the eight mantras beginning with 'Hiranyagarbha' and 'To which deity' establish the single divinity through the elision of the vowel 'e'.
