Core Teaching
The core teaching of Buddhism is Dependent Origination induced by Karma.
Pratītyasamutpāda Gāthā
ye dharmā hetuprabhavā hetuṃ teṣāṃ tathāgata uvāca । teṣāṃ-ca yo nirodha evaṃvādi mahāśramaṇaḥ । ajñānāc cīyate karma janmanaḥ karma kāraṇam । jñānān na cīyate karma karmābhāvān na jāyate॥
Dependent origination can be contrasted with the classic Western concept of causation in which an action by one thing is said to cause a change in another thing.
Dependent origination instead views the change as being caused by many factors, not just one or even a few.
Those dharmas which arise from a cause, the Tathāgata has declared their cause.
And that which is the cessation of them, thus the great renunciant (sramana) has taught.
Through ignorance, karma is accumulated, karma is the cause of (re)birth.
Through knowledge, karma is not accumulated, through absence of karma, one is not (re)born.
The additional verse is Southeast Asia specific (fifth century date) and does not have an equivalent in any Buddhist text, whether in the original Indic language or Tibetan or Chinese translation.
ये धर्मा हेतुप्रभवा हेतुं तेषां तथागत उवाच । तेषांच यो निरोध एवंवादी महाश्रमणः । अज्ञानाच्चीयते कर्म जन्मनः कर्म कारणम् । ज्ञानान्नचीयते कर्म कर्माभावान्न जायते॥
