Abstract
The paradigm of human flourishing proposes to direct efforts in all fields to achieve the development of people at the individual, community, and systemic levels. At the individual level, in recent years, there have been several proposals in the field of health sciences that recognize, among others, two indispensable dimensions for human well-being: meaning and spirituality. This chapter offers a perspective of current studies in which the sciences and humanities converge, updating the interest in spiritual knowledge at the service of human flourishing. We understand that the word spiritual implies a variety of meanings, from religious practices to mental states of tranquility, peace, and purpose of life in a secular sense.
