There is a real need for a Guru if we are undertaking a spiritual journey. But before embarking on a spiritual path, we must honestly determine whether we are ready and whether our need for a guru is genuine. Ask yourselves this question: "Am I committed, or am I just involved?" We do not need a guru if we do not want God.

The complications in life are so great that the poor mind is unable to handle them. When we are moving blindly through the valley of life, stumbling in darkness, we need the help of someone who has eyes, who has been on the path, who has followed it to the end, and who can tell us the right way to go.

Guru is not the body; Guru is light; and Guru is wisdom. Light and wisdom are essential in human life. By divine right, the title of guru is conferred only upon those exalted souls who, through their own Self-realization and oneness with God, are qualified to lead others from the darkness of ignorance to the everlasting light of truth. He is a humble prophet or messenger, invested with the duty of showing the true spiritual way to ordinary people.

God sends the seeker indirect guidance at first, through books and lesser teachers. When the desire for Him is very strong, He sends the help of a Self-realized guru.

There are many who are trying to lead others but who have no right to do so. No one can take you to God unless he himself has found God. The blind can't lead the blind.

There is also a difference between a Guru and a spiritual teacher. A teacher is one who has some experience, who can guide you to a certain point, and who is perhaps capable of transmitting some spiritual power, but he would not be a guru.
That does not mean that spiritual teachers are bad, but they must recognize their limitations. They must see that they do not have all the answers.

There is a need to exercise some prudence to distinguish a true guru from a sea of self-styled leaders. The fake gurus are all over the place, and they can hide themselves very well. It is thus difficult to differentiate between a fly-by-night Baba and a truly evolved Guru.

Each one of us is susceptible to exhibiting docile "cult-follower" behavior in the right/wrong circumstances. People believe that "it can never happen to them" because they want to believe they are stronger and better than the millions who have fallen victim to alleged cult mind control. Mind control is alive and well and in many varied forms across many countries.

A so-called cult will generally target the most educated, active, and capable people it can find. Such beliefs as "others could be made to do that but not me" and "others could be swayed by speeches but not me" are dangerous.
The ease with which this happens is important for both scientific understanding and real-world problems ranging from friends and family in cults to extremist movements. The research by Stanford University, reproduced here, very well proves the same.

But there is a great deal we can do to stay safe, sane, and whole and to help the people we care about.
Spiritual search is indeed the inborn divine right of every human being. Knowledge and education are the birthrights of every human being. Do whatever we want; spirituality is our inner force, which has a constant pull. This pull becomes very strong at times. So strong that man has no choice. But he will have to make the right decision.

Finally, it is God alone who is the true Guru, acting through the agency of souls that are awake in Him and who appear as spiritual advisors, sometimes spiritual masters, for our spiritual ascension-call it spiritual help-once we are ready.

This book can be referred to as a spiritual journey book, advising on how do you go on a spiritual journey and safeguarding against cults and extreme beliefs.
God help you.
