To me the Fool represents the start of the spiritual/magical journey. Yet, in another breath it is the connection between Wisdom (Chokmah) and the Crown (Keter) where we are already at the end. At the start of our spiritual/magickal journey we are closest to enlightenment, to spiritual awakening and yet we do not know this because of our innocence on the path. It is said that children are in this state of being on a daily basis, and perhaps that is why so many spiritual teachers in the past have used the statements of being child like in their writings and talks.
In modern day definition a fool is typically defined as a stupid person or an idiotic person. It is defined as a person who may be weak-minded or lacks judgment. It is an unfair definition that has come upon mankind in general society and may in itself be a definition that lacks judgment. For the Fool in the Tarot and spiritual world is not stupid, nor is he idiotic. Though, as he is at the start of his journey he very well may be mislead by those around him, or not have enough experience to make the best choices.
In a reading the cards all depend upon the cards around them but we can look at each one individually to understand the cards around them, as well as the card by itself. The Fool represents the start of a new journey, this could relate to your spiritual walk, lifestyle, career, or any host of “new journeys” in one's life. The Fool is always eager to begin, to dive right in so to speak and this is always a positive. It reminds us to stay open to the opportunities that life presents us. However, it also is a cautionary card because as mentioned the Fool lacks the experience of life and education. He may lack the necessary discernment needed that perhaps someone who is an adept would already posses. Keep in mind though that the Fool on the Tree of Life is located between Keter and Chokmah so it is the connection between The Crown (just below the three spheres of negative existence) and Wisdom. The Fool must trust his inner connection to the these two facets, to the Divine, to his own Divinity when making these choices. It is a card that is telling us to bravely step forward but be always aware and mindful of one's surroundings.
Question: What is does the Fool say to you? How does the Fool apply to your journey at this point in time?
