Light has value only when there is darkness;

At first look, everyone appears to be a devotee, but individuals respond differently to different circumstances. If you keep a ball of iron and dry leaf side by side,  when there is no wind both of them will be stable and steady. But when there is a breeze, the dry leaf will be blown several miles away. The iron ball however will remain firm. If one has true love and unwavering faith in God, one will be like an iron ball, steady and undisturbed. On the other hand, if one is like a leaf, running away on account of difficulties and problems, how can one claim to be a true devotee? Develop pure and steady love and faith. Light has value only when there is darkness; otherwise it has no value by itself. Therefore, in times of trouble and sorrow, whenever problems arise, evoke the principle of Divinity. The Lord will shed illumination and light in moments of darkness!
