It is the super highway to God
Contrary to what the internet and almost books say – it is very superficially in the body with most of its inner divine aspect lying within They are called chores, vajra and then brahma Nadi
Yogananda has described the location and function of those sheaths appropriately in God talks with Arjuna
This is the place to go for prayers. This is the tunnel which people describe in near death experience.
Without this sushumna opening – one cannot meet God
Why delay ? Go within
Of course you can find thousands of fakes who have read about it and talk about it – but they expose their ignorance and reveal their real intention – money and fame
You need a Guru to open this royal path !
