The Reviver Of the monkeys who gave their lives fighting for Rama

After the war with Rāvaṇa, Indra appeared before Śrī Rāma and asked him what boon he wanted. Śrī Rāma replied that all those monkeys who died in the war should come back to life and the forests in which they lived should abound in fruits and flowers in all the seasons of the year. Indra restored all those monkeys to life and made all the forests in which they lived, green and rich with luxuriant vegetation. Vālmīki Rāmāyaṇa, Yuddha Kāṇḍa, Sarga 129
