The flower of life symbol consists of 19 interlocking circles.
The Number 19
The "astral"body is said to be composed of 19 elements: intelligence; ego; feeling; mind(sense conciousness) five instruments of knowledge; the subtle counterparts of the senses of sight, hearing, smell, taste, touch; five instruments of action, the mental correspondence for the executive abilities to procreate, excrete, talk, walk, and exercise manual skill; and five instruments of life force, those empowered to perform the crystallizing, assimilating, eliminating, metabolizing, and circulating functions of the body. This subtle astral encasement of nineteen elements survives the death of the physical body.
