The Ogham symbol for purity, Ailm, is a Celtic symbol. The Ogham is a realm of trees that were thought to offer knowledge and wisdom to the seeker, and it is a primitive means of communication in Celtic culture. Pure energy, honesty, objectivity, clarity, strength, and good health are all symbols of Ailm.
Its symbol is a fir tree branch, which is one of the nine sacred pieces of wood used for sabbat fire. This evergreen tree represents strength, resilience, endurance, longevity, friendship, honesty, truth, and perceptiveness since it grows tall and straight and thrives in harsh conditions.
The circle of the Ailm symbol is a Celtic symbol that represents the soul’s wholeness, integrity, and purity.
