In plain words

Whoever meditates on space as Brahman attains realms of light that are vast, unobstructed, and free. Wherever space extends, there he roams at will. 'Respected teacher, is anything greater than space?' 'Indeed, there is something greater than space.' 'Please, explain that to me.'

'He who meditates upon space as Brahman—is there anything greater than space, O Blessed One?' 'There is indeed something greater than space.' 'Let the revered one tell that to me.'
