Prahlāda Mahārāja says clearly, nānyaṁ tvad asya śaraṇaṁ bhramato 'nupaśye: "I know that without Kṛṣṇa consciousness, without taking shelter of Your lotus feet, one cannot be happy." One wanders within the universe, life after life, but by the grace of a devotee, a servant of Śrī Caitanya Mahāprabhu, one can get the clue to Kṛṣṇa consciousness and then not only become happy in this world but also return home, back to Godhead. That is the real target in life.
(Srimad Bhagavatam------7:9:44------purport).

ord Caitanya always offered respects to Advaita Prabhu as He would to His father because Advaita was even older than His father; yet Advaita Prabhu always considered Himself a servant of Lord Caitanya. Śrī Advaita Prabhu and Īśvara Purī, Lord Caitanya's spiritual master, were both disciples of Mādhavendra Purī, who was also the spiritual master of Nityānanda Prabhu. Thus Advaita Prabhu, as Lord Caitanya's spiritual uncle, was always to be respected because one should respect one's spiritual master's Godbrothers as one respects one's spiritual master. Because of all these considerations, Śrī Advaita Prabhu was superior to Lord Caitanya, yet Advaita Prabhu considered Himself Lord Caitanya's subordinate.
(Sri Caitanya Caritamrta------1:5:147------purport).

People do not recognize that the real distresses in life are the four principles of birth, death, old age and disease. They are so foolish that they resign themselves to these four miseries, not knowing the transcendental remedy of the Hare Kṛṣṇa mahā-mantra. Simply by chanting the Hare Kṛṣṇa mahā-mantra, one can become free from all misery, but because they are enchanted by the illusory energy, people do not take this movement seriously. Therefore those who are actually servants of Śrī Caitanya Mahāprabhu must seriously distribute this movement all over the world to render the greatest benefit to human society. Of course, animals and other lower species are not capable of understanding this movement, but if even a small number of human beings take it seriously, then by their chanting loudly, all living entities, including even trees, animals and other lower species, will be benefited.
(Sri Caitanya Caritamrta------1:9:39------purport).

Nityānanda Prabhu was requested not to come every year to Jagannātha Purī, although seeing Lord Jagannātha greatly benefits everyone. Does this mean that the Lord was refusing Nityānanda Prabhu a fortunate opportunity? No. One who is a faithful servant of Śrī Caitanya Mahāprabhu must execute His order, even if one has to sacrifice going to Jagannātha Purī to see Lord Jagannātha there. In other words, it is a greater fortune to carry out Śrī Caitanya Mahāprabhu's order than to satisfy one's senses by seeing Lord Jagannātha.
