Listening to someone tutoring about "rainbow",
The teaching of science came to my mind.
The raindrops, the sunshine;
The light that enters and exits the droplets;
The reflection, refraction and light dispersion;
All these formed the rainbow.
But they missed the most important factor,
The radiance of our own mind.
Rainbows need to have eyes in correct position, water droplets, light, radiant mind, all like so for rainbow to appear. Move slightly and rainbow is gone. Never came from anywhere, stayed anywhere, or went anywhere. The rainbow was insubstantial, but vividly displayed. All phenomena are like this.
