। ॥ १४५ ॥
In plain words
Attainment, a real beginning, steadiness, rest, trust, purity down at the seed — for the mind, the supreme sign of every one of these is this: attention held unbroken to nāda, the inner sound.
Close to the Sanskrit
Of accomplishment, beginning, steadiness, rest, trust, and purity of the seed — of the mind — the supreme indicating mark is indeed the continuous joining of attention to nāda.
