There are several practices and beliefs in the larger body of the Feri tradition that are almost universal:

• The Three Souls. As in Huna, from which this concept is derived, Feri postulates the existence of three separate yet interdependent souls as a part of the natural psychic structure of the human being. Although a multitude of different names are used to describe them, they are sometimes called the fetch, the talker, and the Godself. The talker is that part of humans which is self-aware and deals with language, rational thought, and the gathering and dissemination of knowledge. It is the first line of communication with others.  The fetch is emotional, pre-verbal, primal, and childlike. It is concerned with generating and storing energy, with the maintenance of the physical body, with housing memories, and is the first to feel deep emotions, such as fear or falling in love. Finally, the Godself is the eternal part of humans, a direct connection to the Goddess. It is said that the talker cannot speak directly to the Godself as they do not speak the same language; therefore, Feris approach the Godself by way of the fetch using symbolism (art, poetry, music, visualizations, etc.). A central practice of Feri concerns bringing these souls into alignment so they may communicate freely, granting the practitioner a deeper awareness of their own personal Godself and the Goddess.

• The Iron Pentacle. A symbolic and energetic tool that is used to help realign and purify the practitioner in relation to certain concepts with which mainstream culture often has an unhealthy relationship. The points are Sex, Pride, Self, Power, and Passion, and each are meditated on in various ways in order to bring the practitioner's awareness into a state of deeper self-understanding.

• The Pearl Pentacle.  Another energetic tool which takes the essence of the Iron Pentacle (microcosm) and expands it outward (macrocosm). The points of the Pearl Pentacle are Love, Law, Knowledge, Power or Liberty (depending on the lineage, both are traditionally valid), and finally, Wisdom. It is understood that both pentacles are the same pentacle viewed from a different perspective.

• The Black Heart of Innocence. The human being in its natural state, unfettered by the restrictions of society. The Black Heart is primal, sexual, honest, and innocent; some lines teach that its core burns with fierce compassion. It is taught that the Black Heart is achieved only after diligent self-work and comes into being when the points of the Iron and Pearl pentacles are purified and in balance.
