If you think you did something to upset the land, you probably have a good sense of what it is that you did and you probably had that sense while you were doing it.
Think about what you could do to make things right. Perhaps that’s going to the place this happened saying a prayer and give an offering for forgiveness. Ask what you could do to make things right and do it.
If you have an elder or family member to talk to, ask for their guidance. There might be a specific prayer or ceremony that you could do to offer your remorse.
Going forward, it may be in your path to make reparations by being proactive and getting others involved in protecting Mother Earth.
Hope this helps.
