In this article, we discuss the numinosity of play in terms of the origin or unique essentiality of play based on analytical psychology, rather than the evolutionary necessity of it in terms of only biological instinct or innate nature, or as something instilled through education. Attempts to explain play in this way lead to the conclusion that play is healing, and play has a powerful relationship with healing in psychotherapy. We also discuss the still point experience and transference- countertransference and the relationship between the therapist and client regarding intersubjectivity, which are concepts related to the numinosity of play. In conclusion, the essentiality of play, which has an archetypal origin, is numinous and divine and has the ultimate teleology of integration and healing of personality, namely individuation. Other people in close relationships perceive the constellation of archetypal energies in an individual because of the working principle of archetype, and all humankind universally shares it and constellates archetypal energy to the other. This, of course, happens in therapeutic relationships, and finally it brings healing to both the client and therapist involved in archetypal play.
