When the seven colours of the spectrum revolve together, the effect is ‘no colour’; when they stop revolving, the seven colours can be separately identified. When three blades of the electric fan revolve fast and no blade is separately noticeable, they give cool comfort. So too when the qualities of Satwa, Rajas and Tamas (purity, action and inertia) are unrecognisably intertwined, then all that remains is pure happiness and nothing else. Supari (areca nut) is brown; pan (betel leaf) is green; chunam (lime) is white, but, when these three are together chewed, the colour is red! When your three gunas are moderated adequately through spiritual practice, the result is shanti or peace. The lamp is the satwa guna, the wick is tamo guna and the oil is rajo guna. When they are integrated, they give the Light of Wisdom which illumines through all problems. (Sathya Sai Speaks, Vol 6, Ch 27.)
