1.13.47

अहस्तानि सहस्तानामपदानि चतुष्पदाम् । फल्गूनि तत्र महतां जीवो जीवस्य जीवनम् ॥ ४७ ॥

ahastani

phalguni
those who are weak
tatra

Those who are devoid of hands are prey for those who have hands; those devoid of legs are prey for the four-legged. The weak are the subsistence of the strong, and the general rule holds that one living being is food for another.
