Word by word
The verse says
Too bitter, too sour, too salty, scorching, sharp, dry, burning - this is what the driven love, and it brings pain, grief and sickness after it.
In plain words
Everything in this list is an extreme.
Not bitter - too bitter. Not warm - scorching. The complaint is not about any particular taste. It is about intensity.
Rajas is the strand of drive and restlessness, and this is what it wants from a plate. More signal. Something strong enough to be felt through whatever else is going on.
Where you've felt this · at work
You eat something far too spicy at your desk while working, your eyes water, and you keep going. It is not that you were enjoying the taste. You were at a dull point in the afternoon and the food was doing something the work was not. You would never have ordered it on a quiet Sunday.
Going deeper
Intensity rather than flavour is what this verse objects to, and that makes it about a great deal more than food.
Rajas is the strand of movement and restlessness. What it wants is stimulation - something strong enough to register through whatever else is happening. Sharp, hot, sour and burning all do that. They cut through.
Which is exactly why they get chosen at particular moments. People do not reach for extremes when they are settled. They reach for them when something needs covering over or waking up, and the food is being asked to do a job that is not feeding.
The pattern is worth recognising, because it is not limited to eating. Anything you reach for mainly because it is strong - noise, argument, speed - is doing the same work. The sign is always the same. Afterwards you are more tired than you were, and slightly less settled than before you started.
