Final answer:
The text does not expressly describe Princess Bari's emotions during her encounter with the Buddha so it is not possible to give a definitive answer. her reaction could be speculated based on literature norms but remains unconfirmed without specific textual evidence.
Step-by-step explanation:
The feeling Princess Bari has when she first encounters the Buddha is not explicitly provided in traditional stories. However, drawing upon common depictions of encounters with divine or enlightened figures in literature, one might infer that a character in her position could feel a mix of awe and fear. Yet, without a specific passage describing Princess Bari's emotions during this encounter, it is not possible to provide a definitive answer. Her feelings could range from awe and reverence to fear, depending on her perception of the Buddha.
It would be speculative to assume her reaction as the excerpt provided does not contain sufficient information regarding Princess Bari's encounter with the Buddha. The insight provided only alludes to knowledge about the mental states of Buddhist contemplatives, suggesting a state of serenity or enlightenment, but not the emotional responses of individuals like Princess Bari when meeting such figures.
