Adbhutasagara 1.88

If fear is not caused to kings by enemies, it is invariably caused by their own sons or by ministers; / and because of drought, the people migrate to unfamiliar cities, mountains, and rivers.

Now, the determination of natural state and related matters:

Herein, natural state consists in being endowed with tawny-coloured rays appropriate to its own season, possessing unbroken wholeness and typical marks, and occupying places such as the mode of calculation-derived dimensions. Deviation from natural state is unnatural alteration. Smoothness, purity, an excess beyond calculated disc dimension, and distinct, immaculate, spotless, long ray-networks and the like are positive qualities. The opposites of these are defects. Natural state devoid of positive qualities or defects produces auspicious consequences. Possessing positive qualities, it is exceedingly abundant [in auspicious consequences]. Possessing defects, it produces inauspicious consequences. Unnatural alteration devoid of positive qualities or defects produces inauspicious consequences. Possessing defects, it produces abundant inauspicious consequences. In that regard, the determination of auspicious and inauspicious consequences is to be made after evaluating the number, strength, and weakness of unnatural alterations, natural state, positive qualities, and defects.
