Buddhism: Veiling Events & Situations in a Positive Light is Important
The strength, wisdom and cheerfulness that accompany such an attitude to happiness. To regard everything in a positive light or with a spirt of goodwill, however, does not mean being foolishly gullible and allowing people to take advantage of your good nature. It means having the wisdom and perception to actually move things in a positive direction by seeing their best light, all the time keeping your eyes firmly focused on reality.
