[1] Though Geraldes is best known for his oil painting[citation needed], he has also produced sculpture, drawings and large ceramic murals.
His early interest in western and eastern esotericism and spirituality can also be seen as a prime factor in his subject matter, in which he often paints geometric patterns involving cosmic imagery and symbolism of universal significance.
In his book Visions of the Esoteric Power he asserts his belief that "art, science, and the spiritual do not exist in isolation".
There are five levels of movement in Geraldes' works: EARTH, AIR, WATER, FIRE and SPIRIT.
He uses the blues and greens of water and the warm colors for fire to create a feeling of completeness or as an ordered whole.
By this last statement he puts men in a total form of relationship to the five signs of water, air, fire, earth and spirit.
