The heat and dust are symbols of passion and desire. Hence the expression "Love fervor". Is it time to show their passion to the full? The heat can also be a sign of anger, because they rightly say "heated debate" or "In the heat of an argument". You do not respond with anger to the difficulties, rather than with a cool head to understand the reasons for them? Get to the source of the barriers, and do not waste your precious energy on anger.
