Meaning of three modes of material nature

The three modes of material nature – There are three primary colors, namely, red, green, and blue (RGB), and various combinations of these three colors in different proportions give rise to unlimited varieties of colors. Similarly, the material nature also has three modes- sattva (mode of goodness), raja (mode of passion), and tama (mode of ignorance), i.e., SRT. As an artist uses RGB to generate the impression of any other color which he/she wants to portrait, similarly SRT produces 8.4 million different species in this world.
