I feel that ultimately idol worship and paganism etc are going against the fundamental One God in Sikhism. I don't think there is any comprise in the Gurbani for worshiping or praying to any other particular God or God's aside from the One and only watching over us. I don't think there is anything wrong with feeling one with nature since God created everything and feeling a spiritual connection with the elements and surroundings is good for the mind and soul. I am not a schooled Sikh by no means.
