Because learning is a primeval inborn desire.
Anti-matter - Matter - Plasma - Particles - Atoms - Molecules - Compounds in gases, liquids and solids make our being, in a time, of learning. Every moment is a learning and every breath taken, is for the being and living in a community of scholars for the republic of learning. You just cannot be in some other thing. Everyone is, therefore a Sikha unless you are without a brain to mind about the quality or nature of things that make you and surround you. That is why you carefully pay attention to, obey and remember and be inclined to sense, feel, know and understand as you can also feel distressed, annoyed and worried or you can express a strong enthusiasm for something. You can feel concern about things and you regard things as important, when you feel reluctant to do something. Since everything around you is to emphasise a command to avoid injury or an accident. As every remembrance is used to introduce a qualification to a previous event and statement. That is why you bear somethings in mind transiently and keep somethings, always in your mind. Wherever you are, you can just not be, anything else, but the Sikha, you are. Since you are born, with a mind and a body.
This is just a short reminder, that 'The Wild Thing', goes on, in the nature of things and in a state of natures Grant(h) on the True Path of Nature.
