A “Team of Light” refers to the spiritual entities who guide the individual in the corporeal world. Jackson uses this terminology to refer to “the divine.” In Part 1, Chapter 3, she explains that everyone’s Team of Light is made up of God energy, spirit guides, the angelic realm, and loved ones who’ve already crossed over to the Other Side. God energy is “the highest and most powerful source of love,” and is responsible for sending “signs from the universe” (12). Spirit guides and loved ones can also send signs and offer guidance.

Jackson holds that Teams of Light are like guardian angels, or protective forces. The individual can seek their help if they need guidance, feel alone, want answers, or simply need comfort. When Jackson refers to her intuition, gut feelings, or interpretation of signs, she attributes these experiences to her Teams of Light. She argues vehemently against notions of coincidence and chance, and instead holds that our Teams of Light are responsible for arranging synchronous happenings in everyday life.

Synchronicity is a concept that was first coined by Carl Jung. While the layperson (or skeptics of Jackson’s work) might refer to synchronicity as “a meaningful coincidence,” Jackson explains that it is rather a phenomenon which exemplifies “our innate and active connection to one another and to the world around us” (xix). Jung first wrote about synchronicity in his Princeton University Press book aptly titled Synchronicity; and defined the concept as “the concurrence of events that seem to have no causal relationship to each other, yet also seem to be meaningfully related” (64). Jackson argues that synchronous events are orchestrated by our Teams of Light; they are messages sent from the Other Side to guide, comfort, protect, or enlighten us.

Signs are messages that the universe sends to corporeal beings. Such signs can comfort or guide the individual. Jackson holds that they are our Team of Light’s favorite way of communicating. However, they’re “not mandates to take a particular course of action” (200). Rather, signs are simply a way for the Other Side to offer lessons or revelations.

Jackson positions the Personal and Universal Meaning of Signs as a central theme in the text, noting that signs can come in various physical, emotional, or psychological forms. In Chapter 10, Jackson offers examples of “the most common default signs,” or typical physical signs the individual might encounter; these include birds, deer, coins, rainbows, butterflies, electrical events, ladybugs, or numerical sequences among others (61). The individual can choose specific signs to establish communication with a late loved one, or the universe might send signs of its own volition. Other nonphysical signs include synchronous events, intuition, gut feelings, or dreams. Jackson holds that no matter how signs appear, it is important to pay attention to them in order to maintain a connection with the spirit world.
