Brihat Samhita
के चिद्वदन्ति कार्तिक शुक्लान्तं अतीत्य गर्भदिवसाः स्युः । न च तन्मतं बहूनां गर्गऽदीनां मतं वक्ष्ये ॥ २१-०५ ॥
Some say that the days of the appearance of the pregnant clouds immediately follow the bright half of the lunar mouth of Kārttika—October and November. This view is however not in accordance with the views of many writers on the subject. We therefore will give here the views of Garga and others.
