A psychic, almost by definition, has to be a spiritual psychic.
Love, openness, balance, trust, elegance are characteristics of a spiritually developed person. These are very essential for a spiritual psychic.
However, it is not impossible for a psychic to be less spiritual.
If psychic abilities are gained through talent rather than skill, the necessary 'spirituality' circumvents the conscious mind and operates from the subconscious. (This imbalance can be dangerous; the blessing can also be a curse.)
Also, if for some reason a psychic loses the focus from spiritual balance, this kind of 'falling down' can lead to a fractured psychic consciousness, resulting in advanced spirituality in some aspects and loss of spirituality in others.
Realizing core values of spirituality is of utmost importance to a master spiritual psychic.
