Brihat Samhita
अपसव्ये संग्रामः सव्ये सेनासमागमः शान्ते । मृगचक्रे पवने वा सन्ध्यायां मिश्रगे वृष्टिः ॥ ३०-०४ ॥
If either animals should remain quiet or the winds should blow gently on the north side of an army there will be wars in the land; if this should take place on the south side of an army such army will be reinforced; if it should take place on both sides there will be rain.
