Arthashastra
स्थानिक व्यञ्जनं वा रात्रौ तेजन अग्नि युक्तम् एकान्ते तिष्ठन्तं सत्त्रिणः क्रम अभीनीतं राज्ञः कथयेयुः "असौ सिद्धः सामेधिकः" इति ॥
When an ascetic, pretending to be able to find out hidden treasure trove, is seated with his body burning with magical fire at night in a lonely place, his disciples may bring the king to see him and inform the king that the ascetic can find out treasure trove.
