अहं ब्रह्मेतिवाक्यार्थबोधो यावद्दृढीभवेत् ।शमादिसहितस्तावदभ्यसेच्छ्रवणादिकम् ॥ ४९ ॥
In plain words
Until the understanding of what "I am Brahman" means stands firm in you, keep practising — the hearing, the reflection, all of it — with calm and the disciplines that go with it held steady the whole way.
Close to the Sanskrit
As long as the understanding of the meaning of the sentence 'I am Brahman' has not become firm, for that long, accompanied by tranquillity and the rest, one should practise hearing and the rest.
