Why can't I tell you? Because you are vague, because signs are personal and must be interpreted by the person they happen to. Oh and the fact that there is giving tips and suggestions, then there is spoon feeding. That I will not do. If something is important to you then you will be willing to put in the work necessary to figure it out. The beauty of the journey and experience and all that jazz.
So in fewer words, Theia is correct. I can only give suggestions for that which is different for each person. What a color, scent, feather, or animal represent to me will not be the same for you. So there is no indefinate way for me to possibly know. Each practitioner practices differently.
