What If I Had Chosen Differently? Buddha's Wisdom on Forgiving Your Past Decisions

The 'Other Path' Is Only an Illusion

When we regret past choices, we unconsciously believe that 'if I had chosen differently, everything would have worked out.' But according to Buddha's teaching of dependent origination (pratityasamutpada), every event arises from an intricate web of countless conditions. Even if you had made a different choice, different difficulties would have awaited you there.

In psychology, this phenomenon is called 'counterfactual thinking.' Research from the University of California has shown that when people reflect on past choices, they tend to overestimate the benefits of the path not taken while ignoring its risks and difficulties. The happiness we imagine on 'the road not traveled' is a fantasy that cherry-picks only the convenient parts.

Buddha taught his disciples to observe events not as 'how they should have been' but as 'how they came to be.' Consider someone who regrets changing jobs and struggling afterward. Even if they had stayed at their previous position, they would have faced different challenges—perhaps difficult workplace relationships or industry downturns. Every result has its causes and conditions, and the person you were at that time had their own reasons and circumstances for making that choice. Blaming your past self is like judging past decisions with information you simply didn't have at the time.

Regret Is the Second Arrow

Buddha illuminated the structure of suffering through his famous parable of the two arrows. The first arrow is the unavoidable event itself. But the second arrow—the mental reactions of 'that choice was wrong' and 'how foolish I was'—is one you shoot into yourself.

Consider a concrete example. Imagine someone who keeps thinking, 'I wish I hadn't chosen that university.' The university choice itself was a one-time event completed at a single point in the past. Yet by repeating the thought 'if only I hadn't made that choice' every day, they torment themselves for years on end. The first arrow strikes only once, but because the second arrow is shot repeatedly by your own hand, the wound only deepens.

Neuroscience research has also revealed that ruminating on regret repeatedly activates the amygdala, triggering chronic stress responses. In other words, replaying regret harms not only your mind but your body as well. Buddha taught: 'Do not pursue the past. Do not wish for the future.' When you notice regret over a past choice, simply recognize: 'This is the second arrow.' That recognition alone becomes the first step in breaking the chain of regret.

The Truth About 'The Best Choice' Through Dependent Origination

Buddha's teaching of dependent origination states that 'no phenomenon exists in isolation; everything arises in mutual dependence.' When we view past choices through this lens, the very premise that 'I could have chosen differently at that time' begins to crumble.

When you made that choice, countless conditions were at play: your personality, your upbringing, your knowledge at that point, the circumstances around you, your physical condition, your emotional state. Your choice emerged as the result of all these conditions coming together. To have made a different choice, at least one of those conditions would have needed to be different—but that would have required a different version of you, not the person you actually were.

For example, suppose you regret losing money on an investment recommended by a friend. Behind that choice lay your trust in that friend, your expectations about the economy, your understanding of risk at the time, and many other conditions. With all those conditions in place, it was the most natural decision for the person you were then. The law of dependent origination teaches us that 'under those conditions, that choice was inevitable.'

Five Steps to Letting Go of Regret

Here are practical methods for applying Buddha's teachings to everyday life.

Step one: notice the regret. First, simply become aware that 'right now, I am regretting a past choice.' The foundation of mindfulness is observing without judgment. Rather than thinking 'I'm terrible for regretting again,' quietly acknowledge: 'Ah, regret has arisen.'

Step two: objectively review the circumstances. When you made the choice you regret, what information did you have? What was your emotional state? What constraints were you facing? Writing these down on paper helps you see how your past self was making judgments under extremely limited conditions.

Step three: name three things you learned from the choice. Every difficult experience teaches you something. Perhaps a failed career change taught you negotiation skills. Perhaps an unsuccessful relationship helped you discover the values you truly hold dear.

Step four: practice loving-kindness meditation. Close your eyes in a quiet place and visualize your past self in your mind. Then silently repeat: 'May the person I was then find peace. May the person I was then be free from suffering.' Just five minutes of this practice can begin to transform your attitude toward your past self.

Step five: return your awareness to the present moment. Buddha repeatedly emphasized the importance of focusing on 'here and now.' When regret arises, direct your attention to your breathing, notice the sensation of your feet touching the ground, and come back to this present moment. You cannot change the past, but the choices you make in this moment are always in your hands.

The Science Behind Self-Forgiveness

Buddha's teachings are supported by modern psychological research. Studies on self-forgiveness have reported that people who are able to forgive their past choices experience significant reductions in depression and anxiety symptoms, along with improved life satisfaction.

A research team at the University of Texas found that participants in a self-forgiveness program showed an average twenty-three percent decrease in cortisol, the stress hormone, after eight weeks. Additionally, research at UC Berkeley has demonstrated that people who can forgive their own mistakes become more open to new challenges and less likely to repeat the same errors.

Furthermore, Dr. Kristin Neff, renowned for her research on self-compassion, points out that people who are excessively hard on themselves actually find it harder to improve their behavior, while those who can direct compassion toward themselves become capable of making better choices. This aligns perfectly with the compassion practices taught by Buddha. Continuing to punish yourself does not lead to growth—it leads to stagnation.

The Hope Found in Impermanence

Impermanence, which stands at the heart of Buddha's teachings, might seem like a pessimistic concept at first glance. In reality, however, impermanence offers the greatest hope to those of us who suffer from past choices.

Everything continues to change. Your cells are replaced daily, and your way of thinking evolves with each new experience. The 'you' who made that past choice and the 'you' who exists now are different beings sharing the same name. Like a river's current—just as you can never step into the same river twice—you always exist as a new version of yourself.

Remaining bound to past choices is like trying to grasp water that has already flowed downstream. By accepting the truth of impermanence, you can free yourself from the burden of past decisions. Today, you possess different conditions, knowledge, and experiences than yesterday. From this very moment, the freedom to make new choices is always yours.

Forgiving the past is not about approving it. It is not about convincing yourself that 'that choice was right.' Forgiving the past means choosing to end a life controlled by the past and to live fully in this present moment. This is precisely the freedom Buddha sought to convey. You are not a prisoner of past choices—you are the creator of this present moment.
