शतं चैका च हृदयस्य नाड्य- स्तासां मूर्धानमभिनिःसृतैका । तयोर्ध्वमायन्नमृतत्वमेति विष्वङ्ङन्या उत्क्रमणे भवन्ति ॥ १६॥

There are one hundred and one arteries of the heart, one of which pierces the crown of the head. Going upward by it, a man at death attains immortality. But when his prana passes out by other arteries, going in different directions, then he is reborn in the world.
