Bhagavad Gita · 4.36

अपि चेदसि पापेभ्यः सर्वेभ्यः पापकृत्तमः।सर्वं ज्ञानप्लवेनैव वृजिनं सन्तरिष्यसि॥

api ched asi pāpebhyaḥ sarvebhyaḥ pāpa-kṛittamaḥ sarvaṁ jñāna-plavenaiva vṛijinaṁ santariṣhyasi

Even if you are the most sinful of all sinners, you shall cross over all evil by the boat of knowledge alone.
