If you have faith that the soul is the eternal servent of Krishna, then you will have no more misery.
The influence of a pure devotee is such that if someone comes to associate with him with a little faith, one gets the chance of hearing about the Lord from authoritative scriptures like Bhagavad Gita and Srimad Bhagavatam.
There are many societies and associations of pure devotees and if someone with just a little faith begins to associate with such societies, his advancement to pure devotional service is rapid.
Faith in Guru with no faith in his disciples is an illusion.
Unless we hear very strictly with great faith to the order of our Spiritual Master, we will not understand what is the mercy of Krishna and how it is coming upon us.
No amount of study of scriptures, austerity or charity can help us know God. The only way is to follow the footsteps of saintly people. When we have faith in that, that faith shows us the way.
