अन्तराय-उपसर्ग-विवेचनम् / Analysis of Yogic Obstacles (Antarāyas) and Upasargas
नदीनदसमुद्राणां तीरे रथ्यांतरे ऽपि वा । न जीर्णोद्यानगोष्ठादौ नानिष्टे न च निंदिते
nadīnadasamudrāṇāṃ tīre rathyāṃtare 'pi vā | na jīrṇodyānagoṣṭhādau nāniṣṭe na ca niṃdite
河川・小川・海の岸辺でも、また道の真ん中でも、シヴァ礼拝の聖なる行（ヴラタ）を行ってはならない。荒れ果てた庭園や牛舎などでも行ってはならず、不吉で非難される場所でも同様である。シヴァを礼拝する場は、清浄で相応しく、咎なき所でなければならない。

Tattva Level: pashu
Shiva Form: Vāmadeva
Significance: Clarifies deśa-śuddhi for vrata and pūjā: even naturally sacred liminal edges (river/sea banks) are not automatically fit for a specific observance unless properly prepared; emphasizes intentional sanctification of space in Śaiva practice.
