Change arrives whether we invite it or not: a new job, a move, a relationship ending, an illness, the passing of years. Even welcome changes can feel unsettling because they disturb routines and certainty. Much of the difficulty comes from clinging to how things were, or from expecting a permanent state that life never offers.
The Gita responds with a wider view. Gita 2.13 compares the changes of the body to the stages of life, and says the self remains constant through every change of body and circumstance, so the wise are not shaken. Gita 15.16 speaks of the perishable and the imperishable, inviting us to distinguish what changes from what endures and to invest less in passing circumstances. Gita 2.28 says life appears briefly within a larger unseen cycle, which softens attachment, and Gita 9.7 describes endings and beginnings as phases of a greater cycle.
The Gita also gives direction. Gita 15.3 says to cut the deeply rooted tree of attachment with the strong axe of detachment, and not to wait to understand every complication before acting. Gita 11.26 shows even great warriors drawn along by time, so hold titles and rivalries lightly. Gita 11.28 compares beings to rivers flowing toward the ocean, inviting trust in the direction of life. If change brings grief or anxiety, please also talk with a counsellor or trusted person.
