Entering Sakana for the sake of Parnasa:<a href="#_ftn1" name="_ftnref1">[1]</a>
According to all, it is permitted for one to slightly endanger his life for the sake of Parnasa, making a livelihood. Thus, one may go hunting despite the risks that it carries. Likewise, one may travel by ship for the sake of business through risky water despite the fear of shipwreck.
