Sutra 1.29

ततः प्रत्यक्चेतनाधिगमोऽप्यन्तरायाभावश्च॥२९॥
Tuta-ha pratyak-chetana-adhigumo pey-anta-raya-bhavashchuh॥29॥ 

As translated by Hariharananda Aranya, "From That Comes Realization Of The Individual Self And the Obstacles Are Resolved." In the sutra, 'That' refers to the repetition of the Pranava sound, as well as THAT which is the energy of 'Godness' that animates the Universe and is within us as the true Self.
