Memory is certainly superior to ākāśa (space). This is why, if many people get together but their memory fails, then they cannot hear or think or know anything. But if they remember, they can then hear, think, and know. Through memory one knows one’s children and animals. Therefore, worship memory.
‘One who worships memory as Brahman has free movement as far as memory goes.’ Nārada asked - ‘Sir, is there anything higher than memory?’ ‘Of course, there is something higher than memory,’ replied Sanatkumāra. Nārada then said - ‘Sir, please explain that to me’.
