Establish strong mindfulness that can act as a frame for shifting states of mind. Go easy on the mental content letting it all pass through. Aware of a basic luminosity, or vibrancy, assess what is needed to encourage citta – goodwill, patience, dispassion.
Citta has its own basic clarity and sanity. Practice to establish citta on its own ground, where there is no suffering. This is the upright citta, the foundation for all the virtues leading to awakening.
