Rajasic fortitude pursues dharma, pleasure, and wealth — but always with one eye on the reward. There is real steadiness here, real discipline. But the motive beneath it is the expectation of results.
A student who studies hard, but only because they want the top rank — not because they love learning — demonstrates this kind of fortitude. The effort is genuine. The persistence is real. But the driving force is the desire for fruit, not the joy of the work itself.
This fortitude is not bad — it is simply incomplete. It can accomplish a great deal in the world. But because it depends on results, it is fragile. When the reward does not come, this steadiness can crumble.
