In addition to spirit guides, you might get advice from your Higher Self. Your Higher Self is quite different from the spirit guides. The spirit guides are essentially your friends, although sometimes, they give you a lot of trouble. The Higher Self is you. It can be defined as the future you, wiser you or one of the sides of your own personality.
While you are playing on the field and don't know the future, your Higher Self knows the game plan. Often, your Higher Self is your future incarnation. It is the finest version of you which shares much of your personality with you. Yet, since each incarnation has a unique experience, you are somewhat different from other your incarnations. Your higher self includes you and all other your incarnations, past and future ones.
Sometimes, you might be connected to more than one Higher Self, one after another. In this case, your first Higher Self serves for the first part of your life and then another Higher Self moves in and takes charge. That may happen if you have reached a certain level of spiritual development and earned the new lessons and new work assignments, which require additional expertise. However, both of your Higher Selves are part of your own identity, part of your vibration, and part of your branch of the Tree of Life. Both of your Higher Selves would be related to each other.
It is helpful to visualize the tree of life made of light and the souls would be little berries on branches. Your past life, your present life and your future life would be sitting on the same little branch. The image for the past and future life would be 'beads on a string'. Another image would be spheres which all have the same center. The incarnations are like concentric spheres, the past ones are enclosed in future ones. The biggest of the spheres would be the Higher Self.
Some people are in constant communication with their Higher Self. It is helpful to speak to it as frequently as you would speak to God, because it is the personality which is most interested in your progress and which is most tightly related to you. It is you - just a kinder, brighter, stronger and wiser version of you.
When you are creative, when you feel inspiration, energy and happiness rise to a the vibrational level of your Higher Self and receive an additional bliss. In converse, when you feel disconnected and lost, it is likely that you have lost the connection to your Higher Self. A universal tool for reconnecting is meditation.
