These are the five men of Brahman, the door-keepers of the Svarga (heaven) world. He who knows these five men of Brahman, the door-keepers of the Svarga world, in his family a strong son is born. He who thus knows these five men of Brahman, as the door-keepers of the Svarga world, enters himself the Svarga world.

In plain words: These five breaths are servants of Brahman, the ultimate reality, and they guard the door to heaven. Whoever understands them will have a strong son in the family and will reach heaven himself.
