The Lord can award anyone and everyone liberation (mukti) from the bondage of material existence, yet He rarely awards the privilege of love of Godhead, as confirmed by Nārada (muktiṁ dadhāti karhicit sma na bhakti-yogam). This transcendental devotional service of the Lord is so wonderful that the occupation keeps the deserving devotee always rapt in psychological activities, without deviation from the absolute touch. Thus love of Godhead, developed in the heart of the devotee, is a great mystery. Brahmājī previously told Nārada that the desires of Brahmājī are never unfulfilled because he is always absorbed in the transcendental loving service of the Lord; nor has he any desire in his heart save and except the transcendental service of the Lord. That is the beauty and mystery of the process of bhakti-yoga. As the Lord's desire is infallible because He is acyuta, similarly the desires of the devotees in the transcendental service of the Lord are also acyuta, infallible.
(Srimad Bhagavatam---2:9:35---purport).

Lord Caitanya recommended that the greatest achievement of human life is to achieve the grace of the Lord, love of God. He said, premā pumartho mahān: to achieve love of Godhead is the highest perfection of life. The same perfection is recommended by Kardama Muni to his wife. His wife belonged to a very aristocratic royal family. Generally, those who are very materialistic or who possess material wealth and prosperity are unable to appreciate the value of transcendental love of God. Although Devahūti was a princess coming from a very great royal family, fortunately she was under the supervision of her great husband, Kardama Muni, who offered her the best gift which can be bestowed in human life—the grace of the Lord, orlove of God. This grace of the Lord was achieved by Devahūti by the good will and satisfaction of her husband. She served her husband, who was a great devotee and saintly person, with great sincerity, love, affection and service, and Kardama Muni was satisfied. He willingly gave love of God, and he recommended that she accept it and enjoy it because he had already achieved it.
Love of God is not an ordinary commodity. Caitanya Mahāprabhu was worshiped by Rūpa Gosvāmī because He distributed love of God, kṛṣṇa-premā, to everyone. Rūpa Gosvāmī praised Him as mahā-vadānya, a greatly munificent personality, because He was freely distributing to everyone love of Godhead, which is achieved by wise men only after many, many births. Kṛṣṇa-premā, Kṛṣṇa consciousness, is the highest gift which can be bestowed on anyone whom we presume to love.
(Srimad Bhagavatam---3:23:8---purport).

Lord Śrī Rāmacandra is so kind and merciful to His devotees that He is very easily satisfied by a little service rendered by anyone, human or not. This is the special advantage of worshiping Lord Rāmacandra, and there is the same advantage in worshiping Lord Śrī Caitanya Mahāprabhu. Lord Kṛṣṇa and Lord Rāmacandra, in the manner of kṣatriyas, sometimes showed Their mercy by killing asuras, but Lord Śrī Caitanya Mahāprabhu awarded love of God without difficulty even to the asuras. All the incarnations of the Supreme Personality of Godhead—but especially Lord Rāmacandra, Lord Kṛṣṇa and, later, Lord Śrī Caitanya Mahāprabhu—delivered many of the living entities present before Them, indeed almost all of them. Śrī Caitanya Mahāprabhu is therefore represented in the six-armed form of ṣaḍ-bhūja-mūrti, which is a combination of Lord Rāmacandra, Lord Kṛṣṇa and Lord Śrī Caitanya Mahāprabhu. The best purpose of human life can be fulfilled by worshiping the ṣaḍ-bhūja-mūrti, the form of the Lord with six arms-two arms of Rāmacandra, two arms of Kṛṣṇa and two arms of Śrī Caitanya Mahāprabhu.
