The torment of living arises from being separate from love as an enduring state. All the frustration and the search for something to do in life is the endeavour to fill the void and the perennial ache for completion.
The sense of separation from love arises in the time between being born and the gathering of experience. The distance from the womb casts a spell of forgetfulness of a place of untroubled harmony that is never fully erased. The purpose of physical love is to reduce the time from the moment of conception to the immediacy of the present.
The sexual desire for union is an imperative to perpetuate the species but is also, for human beings, the ultimate expression of love as the merging of the male and female principles. This deeply unconscious impulse persists as the prime motivation for union with that which will replicate the timeless love once so intimately known.
