Brihat Samhita
शरदि कमलौदरऽभो हेमन्ते रुधिरसन्निभः शस्तः । प्रावृट्काले स्निग्धः सर्वऋतुनिभो अपि शुभदायी ॥ ३-२४ ॥
If, in Śarada (October, November), of the colour of the centre of the lotus, if, in Hemanta (December, January), of blood color, mankind will be happy. If, in Varṣā (August, September), the rays of the sun be soft, mankind will be happy even though the sun should be of any of the colors mentioned above.
