In a Buddhist view where all things are empty, how can qualities like love, compassion, and empathy be meaningfully understood or justified?

Buddhism teaches that all phenomena are empty of inherent existence (śūnyatā). This includes not only material objects but also the self, other beings, and even emotions and concepts. Yet, the cultivation of love , compassion, and empathy is central to the Buddhist path. Other philosophical or religious systems offer clear metaphysical grounds for love: - In Advaita Vedānta, love is said to naturally arise from the realization that all beings are ultimately the same Self (ātman). - In Bhakti traditions like Vaishnavism or even other theistic religions like Christianity, love is grounded in the belief that all beings are ' divine eternal souls', either a portion of God, or children of God. But Buddhism does not appear to endorse either of these metaphysical views. If everything is empty from a Buddhist perspective, wouldn’t that imply that emotions like love, compassion, and empathy are also empty and devoid of inherent existence? Then why should one love at all? How can these qualities be understood, justified, or cultivated within the framework of emptiness? Looking for answers grounded in Buddhist philosophy, ideally drawing from classical texts or traditional commentaries, to better understand how this seeming paradox is resolved.
