भिन्नं कपालं कट्यां तु सन्धिमुक्तं तथा च्युतम् |
जघनं प्रति पिष्टं च वर्जयेत्तच्चिकित्सकः ||१२||
असंश्लिष्टं कपालं तु ललाटे चूर्णितं च यत् |
भग्नं स्तनान्तरे शङ्खे पृष्ठे मूर्ध्नि च वर्जयेत् ||१३||
आदितो यच्च दुर्जातमस्थि सन्धिरथापि वा |
सम्यग्यमितमप्यस्थि दुर्न्यासाद्दुर्निबन्धनात् [२] ||१४||
सङ्क्षोभाद्वाऽपि यद्गच्छेद्विक्रियां तच्च वर्जयेत् |१५|
मध्यस्य वयसोऽवस्थास्तिस्रो याः परिकीर्तिताः ||१५||
तत्र स्थिरो भवेज्जन्तुरुपक्रान्तो विजानता [१] |१६|
