Although the religious experience can be spiritual, not all spiritual intentions should be submitted to the standards of religiosity. The mystical attitude can be found in philosophy or rational inquiry. As Héctor Sevilla shows, the paradigm of emptiness is typical of those who have made their lives a prose where questions are overcome by silence. In that state, even the idea of ​​awakening must be questioned.

Philosophical Spirituality addresses, first of all, the thought about the real, the illusory and the true offered by the famous Buddhist philosopher Nāgārjuna. Next, the text offers different analyzes of the contributions of Śaṁkara, a commendable Hindu thinker of non-duality. Finally, the work extensively alludes to the spiritual rationality of Nishitani, the climax of the Kyoto school of philosophy.

With his analysis, the author shows us how the authentic love of wisdom can cooperate in the recovery of the conscience of the contemporary human being, rooted in a society so scattered that it has lost attention to the essential.
