Material life is called pavarga because here we are subject to five different states of suffering, represented by the letters pa, pha, ba, bha and ma. Pa means pariśrama, very hard labor. Pha means phena, or foam from the mouth. For example, sometimes we see a horse foaming at the mouth with heavy labor. Ba means byarthatā, disappointment. In spite of so much hard labor, at the end we find disappointment. Bha means bhaya, or fear. In material life, one is always in the blazing fire of fear, since no one knows what will happen next. Finally, ma means mṛtyu, or death. When one attempts to nullify these five different statuses of life—pa, pha, ba, bha and ma—one achieves apavarga, or liberation from the punishment of material existence. (Srimad Bhagavatam--7:13:25--purport).

Birth and death apply to one's embodiment in the material world. Fear is due to worrying about the future. A person in Kṛṣṇa consciousness has no fear because by his activities he is sure to go back to the spiritual sky, back home, back to Godhead. Therefore his future is very bright. Others, however, do not know what their future holds; they have no knowledge of what the next life holds. So they are therefore in constant anxiety. If we want to get free from anxiety, then the best course is to understand Kṛṣṇa and be situated always in Kṛṣṇa consciousness. In that way we will be free from all fear. In the Śrīmad-Bhāgavatam (11.2.37) it is stated, bhayaṁ dvitīyābhiniveśataḥ syāt: fear is caused by our absorption in the illusory energy. But those who are free from the illusory energy, those who are confident that they are not the material body, that they are spiritual parts of the Supreme Personality of Godhead, and who are therefore engaged in the transcendental service of the Supreme Godhead, have nothing to fear. Their future is very bright. This fear is a condition of persons who are not in Kṛṣṇa consciousness. Abhayam, fearlessness, is possible only for one in Kṛṣṇa consciousness.
(Bhagavad-Gita--10:4-5--purport).

When Vāmanadeva appeared before Bali Mahārāja, Bali Mahārāja immediately wanted to offer Him respectful obeisances, but he was unable to do so because of the presence of Śukrācārya and other demoniac associates. The Lord is so merciful, however, that although Bali Mahārāja did not actually offer obeisances but only endeavored to do so within his mind, the Supreme Personality of Godhead blessed him with more mercy than even the demigods could ever expect. As confirmed in Bhagavad-gītā (2.40), svalpam apy asya dharmasya trāyate mahato bhayāt: "Even a little advancement on this path can protect one from the most dangerous type of fear." The Supreme Personality of Godhead is known as bhāva-grāhī janārdana because He takes only the essence of a devotee's attitude. If a devotee sincerely surrenders, the Lord, as the Supersoul in everyone's heart, immediately understands this. Thus even though, externally, a devotee may not render full service, if he is internally sincere and serious the Lord welcomes his service nonetheless. Thus the Lord is known as bhāva-grāhī janārdana because He takes the essence of one's devotional mentality.
(Srimad Bhagavatam--8:23:2--purport).

The path followed by pure devotees, who are well behaved and fully endowed with the best qualifications, is certainly the most auspicious path in this material world. It is free from fear, and it is authorized by the śāstras.
One should not think that the person who takes to bhakti is one who cannot perform the ritualistic ceremonies recommended in the karma-kāṇḍa section of the Vedas or is not sufficiently educated to speculate on spiritual subjects. Māyāvādīs generally allege that the bhakti path is for women and illiterates. This is a groundless accusation. The bhakti path is followed by the most learned scholars, such as the Gosvāmīs, Lord Caitanya Mahāprabhu and Rāmānujācārya. These are the actual followers of the bhakti path. Regardless of whether or not one is educated or aristocratic, one must follow in their footsteps. Mahājano yena gataḥ sa panthāḥ: (cc-2:17:186) one must follow the path of the mahājanas. The mahājanas are those who have taken to the path of devotional service (suśīlāḥ sādhavo yatra nārāyaṇa-parāyaṇāḥ), for these great personalities are the perfect persons.
