ब्रह्मचिन्तनिकाअहमेव परं ब्रह्म वासुदेवाख्यमव्ययम् ।इति स्यान्निश्चितो मुक्तो बद्ध एवान्यथा भवेत् ॥ १ ॥
In plain words
A Brief Reflection on Brahman. "I myself am the supreme Brahman — imperishable, and called Vāsudeva." Be certain of that, and you are free. Otherwise you stay bound.
Close to the Sanskrit
Brahmacintanikā (A Brief Reflection on Brahman). "I alone am the supreme Brahman, imperishable, named Vāsudeva" — thus should one be certain, he is liberated; otherwise he would be bound indeed.
