Tradition describes Siddhartha Gautama as a prince raised in great comfort, carefully shielded from the harsher aspects of life. This protective luxury, however, could not hold forever. During journeys beyond the palace walls, he encountered what later came to be known as the “Four Sights”: an old man, a sick person, a corpse, and finally a wandering ascetic. These encounters shattered the illusion that youth, health, and pleasure could provide lasting security. Aging, illness, and death appeared not as distant possibilities but as universal and inescapable realities. The sight of the ascetic, serene amid renunciation, suggested that there might be another way to live—one oriented toward inner freedom rather than external comfort.

Confronted with these revelations, Siddhartha recognized the limitations of his privileged life. The pleasures of the palace, once taken for granted, now appeared fragile and transient, unable to shield anyone from suffering. This realization stirred deep spiritual questioning: why do beings suffer, and is there a path that leads beyond this cycle of dissatisfaction and mortality? Compassion for all who share this condition intensified his resolve, transforming personal disquiet into a universal concern for the fate of all sentient beings. The contrast between the vulnerability of ordinary life and the possibility of liberation embodied by the ascetic became the turning point of his inner journey.

Moved by this insight, Siddhartha undertook what tradition calls the Great Renunciation or Great Going Forth. At about twenty-nine years of age, he left behind royal status, wealth, his wife, and his newborn son, choosing the uncertain path of a wandering seeker. This departure was not an escape from responsibility but a radical commitment to discover a way out of suffering that could benefit all. For years he pursued rigorous spiritual practice, driven by the conviction that there must be a truth deeper than the fleeting satisfactions of worldly life. That quest ultimately culminated in his enlightenment, through which the problem of suffering and its cessation became the heart of his teaching.
