The Great Epic of the Bhārata dynasty 6.26.42

6.26.42

tasmādajñānasaṃbhūtaṃ hṛtsthaṃ jñānāsinātmanaḥ |
chittvainaṃ saṃśayaṃ yogamātiṣṭhottiṣṭha bhārata || 42 ||

Neither this world, nor the next, nor happiness, is for him whose mind is full of doubt. Actions do not fetter him, O Dhananjaya, who hath cast off action by devotion, whose doubts have been dispelled by knowledge, and who is self-restrained. Therefore, destroying, by the sword of knowledge, this doubt of thine that is born of ignorance and that dwelleth in thy mind, betake to devotion, (and) arise, O son of Bharata.'
