Every relationship with your power animal is unique, and there is no wrong way to communicate with them, You just need to invite them into your life. Make time for your spiritual practice, welcome them and listen with your heart. Honoring them as part of your spiritual practice will encourage them to stay longer. Closing your eyes, with the intention of meeting with them while resting, will help too. Writing and drawing are also ways to find connection to their world. I find it is important to say thank you for your lesson, time or gift, and this will encourage them to stay close as your guide.
