तन्त्रसार (महामाहेश्वर अभिनवगुप्त - तन्त्रालोक का प्रामाणिक सार-संग्रह सटीक)

xxxi account of caguhing or other factors the portion of amāvasyā gets into the portion of pratipat, as a result the duration of the tithi is cut short and therefore the solar eclipse occurs. The eclipse then obliteraters the difference of the knowing subjects, the instrument of knowledge and the objects known ( pramātā, pramāṇa and prameya ), Therefore, the occasion is considered to be very auspicious because it bestows other worldly result.
