Here is a comprehensive summary of the Wikipedia article on "Secular Spirituality":

Secular spirituality describes a spiritual philosophy embraced without adherence to institutionalized religion, focusing on an individual's inner peace, search for meaning, and connection with self, others, and nature. American philosopher Robert C. Solomon characterizes it as "naturalized spirituality" without any "other-worldly" elements, while Cornel W Du Toit highlights its unique compatibility with modern worldviews and its ability to foster community through shared experiences of "awe." This approach emphasizes humanistic qualities like love, compassion, and responsibility, often aiming for personal happiness and helping others.

Practices such as yoga and mindfulness meditation are adapted for personal growth and fulfillment, independent of supernatural beliefs. In the 21st century, technology increasingly facilitates these connections, allowing individuals to explore spiritual dimensions of life beyond purely materialistic views. While proponents like Daniel Dennett connect it to "awe and joy and sense of peace and wonder" separate from religious doctrines, critics sometimes argue that without a theistic or supernatural element, secular spirituality essentially equates to humanism.
