There are those who have a problem with praying "to" a saint; they say we should pray directly to G_d. There are others who feel that we are too insignificant to approach G_d directly, so we must have our prayers delivered "through" one who went before us to the feet of The Master, or "through" an ordained "priest." And then there are others who feel that they have a great friend in Jesus, who walks and talks with them as would a fellow friend or sibling.
I'm not sure what prayer is, but I consider the remembrances of those who loved me in this life to be prayer. I feel their energies infusing me, and I try to channel their examples of behavior.
My mothers did not approve of me, but each of them had certain gifts that were saintly to others. I studied these behaviors, and I try very hard to get past the negative baggage that comes with memories of them to the saintly qualities that I saw them sharing with others. It is often difficult to embrace their saintliness without my demons rearing their ugly heads.
My father thought I was quite a prize, but we were taught, even by him, that there was nothing remotely saintly about him. I still find myself remembering him fondly. Even though I don't "say" prayers to him, I do find myself feeling his presence infusing me with a certain positive energy.
Each of us has a relationship with a different aspect of each person we encounter. Those that have been a saint in one's life may have been pure pain in the life of another. In seeking the Spirit of Wholeness, I steadfastly strive to incorporate the positive from every encounter and hope that my Holy Spirit can keep the demons of destruction at bay. Is this prayer? I think so.
