The quote, “The final goal of all religions is to realise the essential oneness,” refers to the idea that despite the multitude of religions in the world, each with its own set of beliefs, practices, and traditions, they all ultimately aim to help their followers understand and experience the fundamental unity of existence.

This “essential oneness” could be interpreted in many ways, but it generally signifies the interconnectedness and interdependence of all things in the universe. It’s the recognition that everything in existence emanates from a single source, whether one calls it God, the Universe, the Absolute, or any other name.

Different religions may have different paths, but their destination is the same – to realize this essential oneness. This realization, in turn, is expected to lead to a sense of peace, compassion, and love for all beings, as one recognizes that harming another is essentially harming oneself.

In today’s world, this idea is more relevant than ever. With increasing polarization, intolerance, and conflict, the recognition of this essential oneness can lead to greater harmony and peace. It can help break down the barriers of ‘us’ versus ‘them’, as we recognize that we are all part of the same whole.

In terms of personal development, realizing this essential oneness can lead to a more profound sense of empathy and compassion. It can help us to become less judgmental and more accepting of others, as we recognize that they are part of the same universal fabric as we are. It can also lead to a sense of inner peace and contentment, as we realize that we are intrinsically connected to the whole universe, and thus, are never truly alone or isolated.

In essence, the realization of this essential oneness can lead to a more compassionate, peaceful, and harmonious world, as well as a more empathetic, loving, and content individual.
