Warning: Spoilers for A Memory of Light under spoiler text.
Nicola Treehill had this fortelling, back in Lord of Chaos:
The lion sword, the dedicated spear, she who sees beyond.
Three on the boat, and he who is dead yet lives.
The great battle done, but the world not done with battle.
The land divided by the return, and the guardians balance the servants.
The future teeters on the edge of a blade.
Lord of Chaos, Chapter 14 - Dreams and Nightmares
- The lion sword - Elayne
- The dedicated spear - Aviendha
- She who sees beyond - Min
- Great Battle - Tarmon Gai'don
- The return - The Seanchan / the corenne.
- Guardians - The Asha'man
- Servents - Aes Sedai
There is a comparable dream which Melaine and Bair had later in the same book:
[To Rand:]Melaine and Bair dreamed of you Rand on a boat with three women whose faces they could not see, and a scale tilting first one way then the other.
Lord of Chaos, Chapter 19 - Matters of Toh
This seems to suggest that the three women in the dream are Elayne, Aviendha and Min and conversely that Rand is he who is dead yet lives from the foretelling.
Which either fits with his state at the end of A Memory of Light, or that he is Lews Therin respun.
What did the boat mean in the Wheel of Time? I'm assuming it was a metaphor? The closest actual boat I can find is
Rand's refrence to finding a ship as he rides off
but with the "The future teeters on the edge of a blade." / "a scale tilting first one way then the other." the timing seems off.
As Rand successfully negotiated the Dragon's Peace before the Last Battle.
