In the six words used to describe love “Mania” in Classical Greek is the highly aroused and passionate love. Mania as in Maniacal. Mania is the passion that leads to great and, often elaborate acts that show a great depth of feeling. This may be the need to send a dozen, dozen (144) red roses as a show of love, when for another type of person a single rose would say so much more.
This is related to the colour green and can be obsessive and possessive. It is not an accident that we say “Green with envy”. This green mania drive is possessive attachment and ownership of any love object.
