कर्म किञ्चित् क्वचित् काले विपाके नियतं महत्। किञ्चित्त्वकालनियतं प्रत्ययैः प्रतिबोध्यते ॥३५॥
There are some powerful actions whose implementation takes place at a predetermined time, but there is another kind of action whose implementation is not predetermined and gets manifested in an appropriate atmosphere.
