Lord Caitanya's mission is to deliver the fallen souls of this age. In this Age of Kali, practically cent percent of the population is fallen. Sri Caitanya Mahaprabhu certainly delivered many fallen souls, but His disciples mainly came from the upper classes. For example, He delivered Srila Rupa Gosvami, Sanatana Gosvami, Sarvabhauma Bhattacarya and many others who were socially elevated but fallen from the spiritual point of view. Srila Rupa and Sanatana Gosvamis were situated in government service, and Sarvabhauma Bhattacarya was the topmost scholar of India. Similarly, Prakasananda Sarasvati was a leader of many thousands of Mayavadi sannyasis. It was Srila Nityananda Prabhu, however, who delivered persons like Jagai and Madhai. Therefore, Lord Caitanya says, amara 'duskara' karma, toma haite haye. Jagai and Madhai were delivered solely by Nityananda Prabhu's mercy. When they injured Nityananda Prabhu, Lord Caitanya became angry and decided to kill them with His Sudarsana cakra, but Nityananda Prabhu saved them from the Lord's wrath and delivered them. In the incarnation of Gaura-Nitai, the Lord is not supposed to kill demons but deliver them by preaching Krsna consciousness. In the case of Jagai and Madhai, Sri Caitanya Mahaprabhu was so angry that He would have immediately killed them, but Nityananda Prabhu was so kind that He not only saved them from death but elevated them to the transcendental position. Thus what was not possible for Sri Caitanya Mahaprabhu was carried out by Nityananda Prabhu.

"Of all types of worship, worship of Lord Visnu is best, and better than the worship of Lord Visnu is the worship of His devotee, the Vaisnava." (Padma Purana)

"Therefore get up and prepare to fight. After conquering your enemies, you will enjoy a flourishing kingdom. They are already put to death by My arrangement, and you, O Savyasacin, can be but an instrument in the fight." (Bg. 11.33)
