All glories to Śrī Śrī Guru and Gauranga
The ultimate source of all maṅgala is Bhagavan Śrī Kṛṣṇa
Once one king went with some of his ministers into the forest to go for hunting. Somehow one day the king accidentally cut his finger, and all blood was coming out. To the king’s astonishment, one minister started speaking that— “All happens for good”. Hearing this the King became very angry. On the way back when evening was approaching somehow the King lost his track and could no longer find his way out of the dense forest. In the meantime, those tribal people who were in search of an animal or human body to sacrifice in front of Kali Devi came across with this King in civil dress. They immediately bound the king with ropes and brought him in front of the sacrificial priest. But while checking the body of the king, the priest could see that his finger was injured, so the priest was not ready to offer this defective body in front of Devi. So this way the king was realised (saved), and finally he could come to his own palace to meet all with his missing team. The king would mention the whole accident what all happened, and then the king could realise that the minister was right by saying “All happens for good” , because if that accident would not have happened then by now, he would be killed in front of Kali Devi.
Great devotees like Ambarīṣa Mahārāja, Prahlāda Mahārāja they never have any kind of complain or dissatisfaction or fear. When Prahlāda Mahārāja was thrown in front of wild elephants or given poison or thrown from the top of mountain into ocean etc. etc., in spite of all these fearful incidents he was completely free of anxiety or tension. Also, we know the case of Śrīla Ambarīṣa Mahārāja the dangerous situation in which he was put into by furious Durvāsā Muni. Śrīla Ambarīṣa Mahārāja wanted to find out some common solution so that he can protect his ekādaśī-vrata by doing paran on time by the help of one very small drop of water, at the same time he never wanted to transgress the dignity of Durvāsā Muni to give prasādam first to him, but due to his delay in coming back from Yamunā river after taking bath and chanting anik, he was bound to take such decision. But out of furious mood Durvāsā Muni unnecessarily wanted to destroy him without understanding his great serving mood. Bhagavan is always ready to protect his śaraṇāgata Bhakta, so Śrī Sudarśana Chakra of Bhagavan wanted to give severe punishment to Durvāsā Muni, who tried his best to get protection from the attack of Sudarśana Chakra by approaching Śrī Nārāyaṇa. He was rejected by Prabhu because of his great offense unto the lotus feet of Ambarīṣa Mahārāja. He was advised by Prabhu to take shelter unto the Lotus feet of Śrīla Ambarīṣa Mahārāja to save himself from Sudarśana Chakra. Finally, he was bound to take shelter unto the Lotus Feet of Ambarīṣa Mahārāja, whereas Śrīla Ambarīṣa Mahārāja was feeling very shy for this unusual incident and started praying unto the Lotus feet of Sudarśana Chakra to protect the life of Durvāsā Muni in exchange of any of his previous pious activities.
Also Śrīla Jada Bharat ji Mahārāja was arrested by some Vrishal Pati (who was the leader of dacoits having full faith in smarta tantric procedure of sacrifice of any animal body or human body in front of Bhadra Kali to fulfill his own desire). So, this way finally Śrīla Jada Bharat Ji Mahārāja was brought infront of Bhadra Kali to be sacrificed. But still then Śrīla Jada BahratJi Mahārāja was completely free of any anxiety or tension because he had full faith in Bhagavan.
So, from all those incidents we can understand that pure devotees never feel any fear or anxiety in any situation, rather they see everything as the arrangement of the Supreme Lord. Without having this kind of feeling how will it ever be possible to do bhajan.
