Limonene is more of a sativa-leaning terpene, helping to achieve a cerebral medical experience. This is the opposite of the couchlock, body high found with many indicas containing high levels of myrcene, linalool or caryophyllene.
Mindonene is a concept I developed after consuming many high-limonene strains of cannabis.
When you feel the limonene in your mind, you are in a state of mindonene.
When a high limonene content elevates your level of mind and focus, you are in a state of mindonene.
