By Swami Harshananda
Visti is a technical term used in Astrology. Viṣṭi is half of a tithi. The works on astrology have raised it to the status of an ill-formed malignant demoness. Viṣṭi has to be avoided for any auspicious undertaking. Works like the Brhatsamhitā prescribe a Viṣṭivrata to appease her.
- Tithi means lunar day.
