万灯海 Sea Of Lamps

所有供养物当中，灯有个特别的意义，灯代表光明，因为它可以破除一切黑暗。以世间来说，光明可以照亮黑暗，使我们看清楚一切，消除我们的恐惧，指示我们明确的道路。以佛法来说，智慧就是一种光明，我们所以会痛苦、得不到快乐，就是因为没有智慧认识苦乐的真相、了解苦乐的原因，所以佛法的智慧就像一盏灯，当灯亮了，满室的黑暗就不见了。

《佛为首迦长者说业报差别经》》 中记载：若有众生奉施灯明，得十种功德：
一者、照世如灯
二者、随所生处，肉眼不坏
三者、得于天眼
四者、于善、恶法得智能
五者、除灭大闇
六者、得智能明
七者、流转世间，常不在于黑闇之处
八者、具大福报
九者、命终生
十者、速证涅槃

Among all offerings, the lamp holds a special significance. A lamp represents light, as it has the power to dispel all darkness.
In worldly terms, light illuminates the dark, helping us see things clearly, easing our fears, and guiding us along a clear path.
In terms of the Buddha’s teachings, wisdom is like light. The reason we suffer and lack happiness is because we do not have the wisdom to see the true nature of suffering and joy, nor do we understand their causes. Thus, the wisdom of the Dharma is like a lamp—once the lamp is lit, the darkness in the room disappears.

“Sutra Spoken by the Buddha to Elder Shuka on the Differences in Karmic Retribution”  has recorded that:
If sentient beings offer lamps, they will receive ten kinds of merits as follows:

1. Illuminate the world like a lamp.
2. Wherever they are reborn, their physical eyes remain unharmed.
3. They will attain the divine (heavenly) eye.
4. They will gain wisdom to discern good and evil.
5. Great darkness will be dispelled.
6. They will obtain the light of wisdom.
7. In the cycle of rebirth, they will never dwell in places of darkness.
8. They will possess great blessings and fortune.
9. At the end of life, they will be reborn in a good realm.
10. They will quickly attain Nirvana.
