Some 2000 years ago a man by the name of Jesus Christ noted and made clear to the followers that beam of pure love can penetrate even the darkest heart in the Universe.
Basically all great spiritual teachings are somehow connected to the beam of light (or from the heaven, inside or outside, various types of light in your body...) and the good which this light can do for us. This beam of light is more or less used as different name for love. I assume this happens from practicall aspect: it is easier to use/imagine light than love in pe. meditation. (and the result is the same)
There was just a matter of time when this knowledge would materialize in our dimension in a way that even most hard heads would understand and be able to benefit from the use it.
So, great Albert Einstein studied back in 1917 the equilibrium between light and matter. Which, back than, was still purely abstract problem.
Interestingly, he concluded that a strong beam of light will stimulate atoms to emit more light of exactly the same color (wave length) and direction.
You get penetration, sort of speak.
And even more: This is the principle of the laser (Townes). Used to make very concentrated beams of light, heat sources penetrating deeply into matter.
Hm. Light/love/laser. It is completely in our hands how we use this love/light technology. Whether we heal our eyes with enourmously precise laser procedures or we just cut each other with laser-beam weapons.
Love is still the same.
