A thief may dress smartly but within his heart he is extremely fearful. He is always afraid of unseen danger and the chance of being caught. But a law abiding citizen lives a carefree life.
In this world misery afflicts those who mess up with the laws of nature. But those who live as per the injunctions of the revealed scriptures are always happy and hearty. The revealed scriptures such as Bhagavad – Gita, Srimad – Bhagavatam etc. should be our manual for life. If we purchase any equipment then we get a manual with it which contains guidelines to operate the gadget. However instead of following the guidelines if we start using the machine whimsically then it is bound to give problems. Similarly if we go against the teachings of the scriptures and behave recklessly then we are bound to suffer. Those who understand this and prefer leading a spiritual life lead a very cheerful life. But those who decry the scriptures often get bewildered by the material world. Uncertainty of the future makes him restive, frustration wanes his enthusiasm and he feels unloved and uncared.
Dealing alone with the material world is like an infant trying to swim across the ocean. Srila Prabhupada explains, bhayam dvitiyabhinivesatah syat : fear is caused by our absorption in the illusory energy. However if an expert boatman picks up the child and puts him in his boat then the child’s misery vanishes. Krishna, the expert boatmen has sent the boat for us in the form of the scriptures. We just need to take shelter of this boat. We can safely and fearlessly cross over through all trials and tribulations of material existence.
As Srila Prabhupada explains that Abhayam, fearlessness, is possible only in Krishna consciousness.
