I don't agree at all with the saying but it is a good sentence for testing nominalizations.

NEG NMLZ.A-CAUS.weight-be.dead CAUS.giving-be.strong
'What does not press you dead makes you strong by increasing something.'

Na is the ergative preposition. It can be prefixed to a verb to make it antipassive or an actor nominalization.

Mo is an instrumental prefix coding that something is done with one's all weight or body. When instrumental prefixes are added to non-agentive verbs, they have a causative reading.

Le is an instrumental prefix meaning 'by increasing something'.
