I used to think that nothing could drain my Spirit but now I think I'm wrong. Machiventa told us we use up Spiritual energy when we pray or when we send it to each other for healing or something ands that it needs to be replenished inside us. That can be done in the Stillness, like going quietly into the Light and filling up with love energy. I do think of it as "up" in the sense of higher vibration. It's not forcing it but more like letting it happen.
I get drained, my human self, from negativity and untruth. There are a lot of things these days to bring a person down. I think it is our job now to strengthen the aspects that we use to build peace, love and harmony in Oneness, as Amundson suggested.
