15: The Secret Doctrine says:
1. The Universe is in reality but a huge aggregation of states of consciousness.—S.  D., II, 633.  I, 70, 626,
2. Spirit and consciousness are synonymous terms.—S.  D., I, 43, 125, 349, 350, 592, 593.
3. Every atom in the universe is endowed with consciousness.—S.  D., I, 105.  II, 709, 742.
4. Six types of Consciousness as embodied in the Kingdom of Nature on the five planes of Human Evolution.—S.  D., I, 123.  II, 678.
a. The Mineral Kingdom 1.
Intelligent activity.  All atoms show ability to select, to discriminate intelligently under the Law of Attraction and Repulsion.—S. D., I, 295.
b. Vegetable Kingdom 2.
Intelligent activity plus embryo sensation or feeling.
c. Animal Kingdom 3.
Intelligent activity, sensation plus instinct, or embryo mentality.—S. D., III, 573, 574.
These three embody the sub-human consciousness.
d. Human consciousness 4.
Intelligent activity, love or perfected feeling or realisation and will, or intelligent purpose.  The three aspects.  S. D., I, 215, 231.—S. D., II, 552.  III, 579.
This is Self-Consciousness—the middle point.—S. D., I, 297.
e. Spiritual Consciousness 5.
Buddhic realisation.  The unit is aware of his group.  The separated unit identifies himself with his ray or type.—S. D., III, 572.  I, 183, 623.
f. Atmic Consciousness 6.
The consciousness of the unit of the Septenary solar system.—S. D., II, 673.  II, 741.
These two embody super-consciousness.
The seventh type embraces them all and is God Consciousness.—S. D., II, 740 note.
