One Vehicle is a central concept in Mahayana Buddhism that emphasizes the unified path of enlightenment accessible to all beings. This term underscores the Mahayana perspective that there is a single, inclusive vehicle leading to Buddhahood, contrasting with earlier schools that viewed enlightenment as achievable only by a select few through specific practices. It promotes the idea that everyone, regardless of their background or previous spiritual achievements, can attain liberation through compassion and wisdom.
