Brihat Samhita
आषाढ्यां समतुलिताधिवासितानाम् अन्येद्युर्यदधिकतां उपैति बीजम् । तद्वृद्धिर्भवति न जायते यदूनं मन्त्रो अस्मिन्भवति तुलाभिमन्त्रणाय ॥ २६-०१ ॥
On the day when the Moon passes through the asterism of Uttarāṣāḍha in the lunar month of Āṣāḍha, the Jyotiṣaka shall weigh quantities of all seeds; if on weighing them again on the next day, any seeds should be found to weigh more, these crops will flourish. The weighing should be accompanied with following mantras to be addressed to the weighing-machine.
