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.
Here is Groves of Stone's text: Battle: Even if this unit is not at the current battlefield, bow this Shugenja unless he is Earth: Give the current battlefield's province +4 or -4 strength.
If this is attached to an Earth shugenja who is bowed, can you still use the ability?
Thanks for your time!

Yes, you can.
The cost is waived and does not require an unbowed Shugenja.
