We have natural polarities in how we think about our bodies. Right/left; Front/back, inner/outer to name the most obvious. When we work with the Sense of Hearing, of Seeing and also, for some people, the sense of smell, you may need to visit 2 animals. In many ways, the journey is like the Polarity Journey in first year, as far as the structure goes.
You may meet a single animal for Touch and for Taste. Usually people do. It is a straightforward calling of a single animal guide.
If you feel drawn to explore these senses in more depth and more specificity, call for a guide and check with your guide if this is appropriate. It is possible to meet all sorts of aspects in the senses. However, the purpose is not show how much you know about the senses or how many taste bud types you have but for you to sincerely engage with what needs healing in you around your senses.
So, if your guides suggest to you that you meet different aspects, great. Use the skills you developed in first year with gathering animals into a council or as you did with polarities to guide and journey.
If there are a number of animals, check that they are not appearing because of a split in the aliveness of that sense. Usually, for instance, if you meet 2 or more animals in a chakra, it is because the aliveness has had to split for some reason and you may need to return to that original experience in order to begin the natural wholeness of that aliveness.
But if you need to journey to each type of taste bud, great. Do invite them to meet. Participate with them in the meeting. Invite them to merge so that you get an opportunity to experience the wholeness of that sense.
Always remember that these are guidelines. The actual journey is alive, specific to the moment in time, impacted by the relationship the journeyer has with their guides, with whatever needs healing. It is also impacted by the presence you have, the places in yourself you have met/healed/accepted and ejected.
Return to the fundamentals of guiding if you feel lost. You already have worked on many of the skills you need to guide whatever variation appears in these journeys.
