Brihat Samhita
के चिद्यथाभिवृष्टं दशयोजनमण्डलं वदन्त्यन्ये । गर्गवसिष्ठपराशरमतं एतद्द्वादशान्न परम् ॥ २३-०४ ॥
Some writers say that the subsequent rainfall will be confined to the spot where the first shower falls; others say that the extent of the subsequent rainfall will be 10 yojanas all round; but according to Garga, Parāśara and Vasiṣṭha, the extent is 12 yojanas.
