Meaning: This quote by Thomas Merton delves into the concept of spiritual integrity and the idea that one's life is ultimately defined by the spiritual or non-spiritual values they uphold. By asserting that "A life is either all spiritual or not spiritual at all," Merton suggests that there is no middle ground when it comes to spirituality; it is an all-encompassing aspect of one's life, influencing every decision and action.

The quote is based on the biblical verse from Matthew 6:24 which states, "No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money." Merton extends this concept beyond the dichotomy of serving God or money, emphasizing that one's spiritual commitment cannot be divided or compartmentalized. This echoes the idea that one's allegiance cannot be divided between spiritual and material pursuits; it is an all-or-nothing proposition.

Merton's statement also emphasizes the idea that the ultimate purpose or goal one lives for shapes their life. He suggests that the end or goal an individual seeks to attain is the driving force behind their actions and decisions. If the end is a spiritual one, then the entire life becomes oriented towards spiritual pursuits. Conversely, if the end is materialistic or non-spiritual, then the life will be shaped by those values.

Furthermore, the quote touches upon the concept of desire and its role in shaping human identity. Merton asserts that individuals are made in the image of what they desire, suggesting that our deepest desires and aspirations define who we are. This aligns with the idea that one's values and priorities reflect their true nature. If spiritual growth and enlightenment are the primary desires, then the individual's character and actions will reflect these aspirations.

Thomas Merton, the author of the quote, was a Trappist monk and a prolific writer on spirituality and social justice. His writings often explored the intersection of contemplative spirituality and the challenges of modern life. Merton's own spiritual journey and his deep engagement with contemplative practices informed his perspective on the all-encompassing nature of spirituality in human life.

In conclusion, Thomas Merton's quote encapsulates the idea that spirituality is not a compartmentalized aspect of life but rather an overarching force that shapes one's identity, values, and actions. It emphasizes the indivisibility of spiritual commitment and the profound influence of one's ultimate goals and desires on the course of their life. Merton's insight serves as a reminder to prioritize spiritual integrity and to align one's desires with higher, more transcendent purposes in order to live a truly fulfilling and meaningful life.
