Generally speaking, the ultimate message of Buddhism is that you possess buddhanature. In other words, you already and quite naturally have within you the qualities of complete enlightenment. But you need to realise this. The fact that you don’t have this realisation is the reason why you are wandering in samsara. According to Nāgārjuna, the Buddha didn’t say that you need to abandon samsara in order to gain enlightenment. What he said was that you need to see that samsara is empty, that it has no inherent existence. This is the same as saying that you need to recognise your essential buddhanature.
