Twelve Fold Chain

The Twelve Chains leading up to the Twelve Stages of Transcendent Dependent Origination

1. Ignorance leads to choice.
2. Choice leads to Consciousness.
3. Consciousness leads to Name and Form.
4. Name and Form lead to the Senses.
5. The Senses lead to Contact.
6. Contact leads to Sensation.
7. Sensation leads to Desire.
8. Desire leads to Attachment.
9. Attachment leads to Existence.
10. Existence leads to Birth.
11. Birth leads to Death.
12. Death.

or as Buddha himself said, "Thus, monks, with ignorance as proximate cause, volitional formations [come to be]; with volitional formations as proximate cause, consciousness; with consciousness as proximate cause, name-and-form; with name-and-form as proximate cause, the six sense bases; with the six sense bases as proximate cause, contact; with contact as proximate cause, feeling; with feeling as proximate cause, craving; with craving as proximate cause, clinging; with clinging as proximate cause, becoming; with becoming as proximate cause, birth; with birth as proximate cause, suffering" the twelve fold chain (as named by The Books) are the aforementioned obstacles which give way to the Twelve Stages of Transcendent Dependent Origination which ultimately leads to enlightenment. The twelve fold chain is not the end of Buddha's idea, he goes on to say "with suffering as proximate cause, faith; with faith as proximate cause, gladness; with gladness as proximate cause, rapture; with rapture as proximate cause, tranquility; with tranquility as proximate cause, happiness; with happiness as proximate cause, concentration; with concentration as proximate cause, the knowledge and vision of things as they really are; with the knowledge and vision of things as they really are as proximate cause, revulsion; with revulsion as proximate cause, dispassion; with dispassion as proximate cause, liberation; with liberation as proximate cause, the knowledge of destruction." Or in other words, The twelve stages of transcendent dependent origination consist of:

(1) suffering which gives rise to
(2) faith which gives rise to
(3) gladness (or joy) which gives rise to
(4) rapture which gives rise to
(5) tranquility which gives rise to
(6) happiness which gives rise to
(7) concentration which gives rise to
(8) the knowledge and vision of things as they really are which gives rise to
(9) revulsion (or disenchantment) which gives rise to
(10) dispassion which gives rise to
(11) liberation (or emancipation) which gives rise to
(12) the knowledge of the destruction of the defilements.

This proves the assumption made by many, that the The Books' lyrics which are commonly thought of as random and/or nonsensical often contain a strong Buddhist undertone. As for songs like "An Animated Description of Mr. Maps" I'm relatively sure most of that is just random.
