Srimad-Bhagavatam: Canto 1 - Chapter 1 - Verse 17


इति स्म राजाध्यवसाययुक्त:प्राचीनमूलेषु कुशेषु धीर: ।उदङ्‍मुखोदक्षिणकूल आस्तेसमुद्रपत्‍न्‍या: स्वसुतन्यस्तभार: ॥ १७ ॥


iti sma rājādhyavasāya-yuktaḥprācīna-mūleṣu kuśeṣu dhīraḥudaṅ-mukho dakṣiṇa-kūla āstesamudra-patnyāḥ sva-suta-nyasta-bhāraḥ


In perfect self-control, Mahārāja Parīkṣit sat down on a seat of straw, with straw-roots facing the east, placed on the southern bank of the Ganges, and he himself faced the north. Just previously he had given charge of his kingdom over to his son.


The River Ganges is celebrated as the wife of the sea. The seat of kuśa straw is considered to be sanctified if the straw is taken out of the earth complete with root, and if the root is pointed toward the east it is considered to be auspicious. Facing the north is still more favorable for attaining spiritual success. Mahārāja Parīkṣit handed over the charge of administration to his son before leaving home. He was thus fully equipped for all favorable conditions.
