This quote offers a profound and somewhat challenging interpretation of religious devotion, emphasizing the importance of inner spirituality over external idolization. It suggests that true worship in any religious tradition should be oriented towards the divine essence within oneself—referred to here as the 'Self'—rather than merely venerating the historical religious figures as separate entities. By stating that Christians, Muslims, and Hindus should worship the Self as Christ, Mohammed, and Krishna respectively, the quote pushes a mystic or nondual understanding of faith, where the divine presence is not external or distant but inherently part of the individual's own being.

This approach encourages introspection and self-realization as the path to connecting with the divine. It challenges the conventional notion of worship that often centers around rituals, scripture, and the idolization of saints or prophets as external authorities. Instead, it promotes a spiritual awakening that acknowledges the sacredness of the 'Self'—the deeper, spiritual identity that transcends personas and dogma.

From a broader perspective, this quote also suggests an underlying unity among the seemingly distinct religious traditions by revealing a common spiritual truth: the path to God or the divine is ultimately an inward journey. It nurtures the idea that each religious figure symbolizes a state of enlightened selfhood, a model for adherents to embody through self-awareness and personal transformation. This idea aligns closely with many mystical traditions, which often perceive religious figures not only as historical personalities but as symbols pointing towards universal spiritual principles.

Ultimately, the quote calls for a more personal and experiential engagement with faith, where believers embrace and honor their own spiritual nature as the living embodiment of the divine presence represented by their religious icons.
