A Buddha (video) means an Enlightened Master, who is a living being with human emotions. Besides having the emotions of an ordinary human, a Buddha also has wisdom. There is only a slight difference between us and a Buddha; we, too, have wisdom but it is yet to be opened. A person who has his/her wisdom fully opened is a Buddha. Once our wisdom is fully opened, we, too, will become Buddhas.
Wisdom is an intangible power; the Buddha Nature is an intangible quality. Therefore, the power of a real Master is also intangible. Being intangible does not mean being nonexistent. We can feel, know, and understand that this power really exists. Without this power, it would largely be a waste of time practicing any method.
In the Buddhist scriptures it is mentioned that the Buddha speaks only with one language, but every being can perceive it according to his own understanding. Now this language is not the ordinary verbal language, it is a kind of sound, of inner vibration, that everyone can use to communicate with each other, and the Buddha can use it to communicate with sentient beings. If we think that it is the language of our world, then it is impossible. Because no matter how intelligent the Buddha is, He can only speak one language at a time. And it is impossible for all beings to listen to all languages at the same time, including animals and lower beings that also understand it. So this must mean the Word in the Bible. Also in Taoism, in the Tao Te Ching, Lao-tzu mentioned that this name we cannot name, the Tao cannot be explained, we can hear it without our ears, we can see it without our eyes, we can perceive it without our sense organs. Now this Word, sound or vibration, is the creative force of the universe. All the scriptures, if you read carefully, mention this Sound, and this so-called inner music.
