puṣpe phale vā vikṛte rājño mṛtyu tathādiśet.
anyeṣu caiva vṛkṣeṣu vṛkṣotpāteṣvatandritaḥ .. 232.12 ..

Where the fruits and flowers of trees undergo change the sovereign is sure to die. Such ill forebodings should be averted. The tree in which the above signs appear should be covered with clothe and adored with sandal, incense and then an umbrella should be stretched over it. Then Lord Śiva should be worshipped and an animal should be sacrificed near the tree.—12-14
