What actually are the Disadvantageous Mental States?

Cut Short:
Mental states mixed or joined with any form of even diluted hate are Disadvantageous!
Mental states mixed or joined with any form of even diluted greed are Disadvantageous!
Mental states mixed or joined with any form of even diluted ignorance are Disadvantageous!

In Detail:
At whatever occasion any disadvantageous thought pertaining to the sense sphere,
accompanied by gladness & associated with knowledge, pointed to any sense object,
such as a visible form, a sound, a smell, a taste, a touch, or a mental object, then right
at that time arises momentarily: Contact, feeling, perception, intention, idea, directed
thought, sustained thinking, joy, happiness, one-pointedness of the mind, the ability of
faith, energy, awareness, concentration, understanding, the ability of mind & gladness,
the ability of vitality, wrong view, wrong motivation, wrong effort, wrong awareness, and
wrong concentration. There arise the powers of conviction, enthusiasm, acute awareness,
focused concentration, understanding. There arise the evil powers of no-shame, of no-fear
of the consequences of wrong-doing! There arise greed, hatred, confusion, & possessiveness.
There arises then wrong view, but neither shame, conscience nor any fear of wrongdoing...
Calm, insight and non-distraction is present. These & whatever formless immaterial mental
states these later causally produce: These are the Disadvantageous mental states...
