'Fetch me from thence a fruit of the Nyagrodha tree.' 'Here is one, Sir.' 'Break it.' 'It is broken, Sir.' 'What do you see there?' 'These seeds, almost infinitesimal.' 'Break one of them.' 'It is broken, Sir.' 'What do you see there?' 'Not anything, Sir.'

In plain words: The father asks his son to bring a fruit of the banyan tree (Nyagrodha) and break it open. Inside are tiny seeds. When the son breaks a seed, he says he sees nothing at all.
