A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

Your Past reads:
As a Focus Effect, after you win this duel, draw a card. Invest : If the Sensei is yours, you may use its abilities a second time this turn. Open: Bow or straighten a target Sensei.
Per Oracle, the holding Honored Sensei has the Sensei keyword.
Would I be able to use Your Past to unbow a bowed Honored Sensei?
Thanks!

The text in the Oracle was incorrect, thank you for pointing this out.
Your Past will not unbow an Honored Sensei.
