Nidāna

Nidāna (devanāgarī: निदान) is a Sanskrit and Pali word that means "cause, foundation, source or origin." In Buddhism the term is associated to the concept of dependent origination (pratītyasamutpāda) that explains the existence of objects and phenomena as being due to a chain of 12 causes/effects called "nidānas."

The Twelve Nidanas

The concatenation of twelve nidanas as described in Buddhism is as follows:

1- From spiritual ignorance (avidyā) arises mental formations (saṃskāra).

2- From mental formations arises consciousness (vijñāna).

3- From consciousness arises name and form (nāmarūpa).

4- From name and form arise the sense organs and their objects (ṣaḍāyatana).

5- From sense organs and their objects arises contact (sparśa).

6- From contact arises sensation (vedanā).

7- From sensation arises craving (tṛṣṇā).

8- From craving arises clinging (upādāna).

9- From clinging arises becoming (bhava).

10- From becoming arises birth (jāti).

11 & 12- From birth arise aging and dying (jarāmaraṇa).

In Stanza I, sloka 4 of The Secret Doctrine the nidanas are called "the great causes of misery". Mme. Blavatsky defined them as follows:

The twelve Nidanas or causes of being. Each is the effect of its antecedent cause, and a cause, in its turn, to its successor; the sum total of the Nidanas being based on the four truths, a doctrine especially characteristic of the Hînayâna System.* They belong to the theory of the stream of catenated law which produces merit and demerit, and finally brings Karma into full sway. It is based upon the great truth that re-incarnation is to be dreaded, as existence in this world only entails upon man suffering, misery and pain; Death itself being unable to deliver man from it, since death is merely the door through which he passes to another life on earth after a little rest on its threshold—Devachan.
