Preparing for initiation means taking spiritual life seriously and when one is convinced that this material world has nothing to offer, it is just for the body. Material world is going to offer everything for the body but not for the soul.
Then what about the soul ? That is preparing for initiation- “I want to do something for myself. What is that something that I want to do for myself ? That I want to advance in my spiritual life.”
Srila Prabhupada says that if we want to learn carpentry, how do we learn? By working under a good carpenter. How can we become a doctor? By working under a doctor and reading the medical books available. Similarly, if we want to do something for ourselves, if we want to become spiritually advanced, then we need a Spiritual Master who can teach us how to advance in our spiritual life.
What are our shortcomings? How can we go in the right direction ? A Spiritual Master can put us on track again and having a Spiritual Master means having a well wisher, our guardian, who serves his disciples. A Guru, helps us, holds our hand and brings us to Krishna. So preparing for initiation means taking help from the Spiritual Master to advance in the spiritual life.
Srila Rupa Goswami in Sadhna Bhakti, says that
“Aadau Guru Padashraya”
Aadau means right in the beginning, we have to find a proper Guru and take shelter of him.
“Aadau Guru Padashraya Krsna dikshaadi”, then Krishna Diksha, Diksha into Krishna Consciousness. Then “Vishrambhena Guru sewa”, serving our Guru, without any doubt.
Preparing for initiation means that we have to fix the teacher then we can advance. The following things we to follow, 4 regulative principles, 16 rounds and studying the recommended Vedic Literature, few books and prepare ourselves.
We have to accept “Vartamana Pad-Pradakshika Guru”, Siksha Guru, Diksha Guru, Chautha Guru, Guru means many Gurus so it is not that Diksha Guru is all in all, there are many other ways Guru comes to us and topmost Guru is Krsna, Chaitya Guru.
“Krsnam Vande Jagat Guru”. Krishna is the topmost Guru. So this is preparing for initiation.
