Gradual Flow of Life within The Spirit
Just like the initial stage of the Earth was gas, later, it formed into its current form; other beings were initially fine delicate particles also. Then, gradually added to their mass, they become bigger and bigger and gain capacity and form. When their capacity and form become relatively complete, and for example, they turn into a full figure human, a lion, a mouse, or a worm, they will benefit from the ethereal gas and the spirit of the universe (according to their capacity). Also, we have already proven how their intelligence is created and established.
