न योगेन न साङ्ख्येन कर्मणा नो न विद्यया ।ब्रह्मात्मैकत्वबोधेन मोक्षः सिध्यति नान्यथा ॥ ५८ ॥
In plain words
Not through yoga, not through Sāṅkhya, not through ritual action, not even through book-learning — liberation happens only through realizing that Brahman and your own Self are one. There is no other way.
Close to the Sanskrit
Not by Yoga, not by Sāṅkhya, not by [ritual] action, nor by [mere] learning — but by the realization of the oneness of Brahman and the Self, liberation is accomplished; not otherwise.
