Spiritual philosophy is any philosophy or teaching that pertains to spirituality. It may incorporate religious or esoteric themes. It can include any belief or thought system that embraces the existence of a reality that cannot be physically perceived. Concepts of spiritual philosophy are not universal and differ depending on one's religious and cultural backgrounds. Spiritual philosophy can also be solely based on one's personal and experiential connections.

The notions of spiritual philosophy, for some individuals, diverge from the long-standing history and tradition of institutionalised religion with believers of faith using the practices, beliefs and rituals of their organised religion to connect with their spirituality. In these instances, the practice of spiritual philosophy centres around the idea of god/gods or the divine.

However, spiritual philosophy is not always defined by religion. One's beliefs in spiritual philosophy can be nontechnical and relate to one's individual views and beliefs outside religious frameworks, regardless of one's stance on religion.

Whilst the notions of spiritual philosophy are based on widely versed concepts and values (in both religious and non-religious instances), the belief system that influences spiritual philosophy is unique to the individual.

Spiritual philosophy can be observed and practiced both intuitively and speculatively.

Intuitive spiritual philosophy suggests that there is an intellectual component beyond conscious inclination that fundamentally influences one's practice of spirituality. This level of intuitive thinking is influenced by one's social identities, with priorities being placed on physical intuitions over rational intuitions.

Speculative spiritual philosophy focuses on critical reflection on theoretical and personal knowledge to gain understanding and alternative viewpoints of the concepts of spiritual philosophy. The main purpose of speculative spiritual philosophy is to understand the reasoning behind reality through profound experiences.

Spiritual philosophy has both religious and non-religious connotations. The spirituality of religious individuals is greatly influenced by their religion's beliefs, teachings, including sacred texts, and the practice of key rituals.
