All beings share a common 'causal' public chain, which contains the ledger of all beings' actions, including all of humanity. The principle of this ledger is causality, which not only records all actions but also every thought and intention, whether big or small, significant or trivial, all recorded without omission; moreover, this public chain features the most intelligent smart contracts, where everything that occurs is automatically executed by causality.

Attempting to leave this 'public chain' and cross-chain to a higher-dimensional 'ledger' (Western Pure Land) is extremely difficult. Throughout human history, those who have achieved this feat are few and far between. Successfully crossing chains to a higher-dimensional public chain, in simpler terms, is akin to spiritual practice.

Those who successfully cross chains become 'immortals'/'Buddhas'. The path of cross-chain is what the Buddha referred to as 'awakening'. Interestingly, according to Buddhist teachings, all beings possess the ability to cross chains; it is 'inherent', requiring no external pursuit. Beings trapped on this chain are essentially equal (all beings are equal), all possess the potential for awakening, yet due to 'distorted dreams', they are unable to enter the 'higher-dimensional ledger'.
