Astanga Hrudaya
आयुर्वेदफलं कृत्स्नं यदायुर्ज्ञे प्रतिष्ठितम् । रिष्टज्ञानादृतस्तस्मात्सर्वदैव भवेद्भिषक् ॥ १३१ ॥
Importance of having the knowledge of rista i.e. fatal signs, for a physician: In the physician who understands the knowledge of life, the entire effects of Ayurveda is treasured; without the knowledge of Rista (fatal signs) it is incomplete; hence the physician should always be well conversant with it.
