The World Is Full Of Noise
The current era is more self-centric and the grossness of humans is influencing and reflecting on each other thus creating and accelerating evilness, things are getting worse and better at the same time, although the worse is more apparent because it makes so much noise.
There is a urgent need of a true spiritual path to protect ourselves from the outer grossness, otherwise there are good chances to fall down spiritually, A true spiritual teacher becomes inevitable for us to safeguard ourselves to uplift us and put us on a safe zone.
A true spiritual teacher does not have anything to teach in the conventional sense of the word, does not have anything to give or add to you, such as new information, beliefs, or rules of conduct. The only function of such a teacher is to help you remove that which separates you from the truth of who you already are and what you already know in the depth of your being. The spiritual uncovers and reveals to you that dimension of the inner depth that is also peace.
If you go to a true spiritual teacher looking for stimulating ideas, theories, beliefs, intellectual discussions, then you will be disappointed. In other words, if you are looking for food for thought, you won't find it, And you will miss the very essence of the teaching, they point that what is deeper, and infinitely vaster than thought, they don't belong to any one religion or spiritual tradition, but are immediately accessible to the whole of humanity.
So when you follow and listen to a true teacher, you feel inner peace arising and stillness around you, their only duty is to transformation human consciousness by shredding off all that is unwanted from the seekers.
