One should never come in contact with degraded person. By avoiding such contact one succeeds in acquiring a long life. One should never indulge in sexual intercourse at day time. Nor should one know a maiden, or a harlot nor a barren woman.
संसर्ग च न गच्छेत तथाऽऽयुर्विन्दते महत्॥ न दिवा मैथुनं गच्छेन्न कन्यां न च बन्धकीम्।
