Over the course of time, though, they began behaving in various unskillful ways.

Tarayana (the starry vehicle) arose after humanity left Old Earth; it concentrates on the psychology of freeing one's mind from unskillful ways.

It stands for strenuous and sustained effort to overcome unskillful ways (akusala dhamma), such as indulging in sensuality, ill will and harmfulness (see, e.g., ahiṃsa and nekkhamma).

In each person lie potentialities that remain inchoate as a result of the individual being caught up in mechanical, neurotic modes of behaviour where energy for personal spiritual development is not used effectively nor efficiently, but squandered in unskillful ways.
