Yes, your are right it can be useful to write short summary, but in the other had it is pretty short video.
However, it starts with the question like : Why yogis have long hair and beard ? Sadhguru answers in a charming and funny way that every man have beard (I am not so sure about this but let's say that most have), and that he just does not do anything about that while most of the man remove it, so perhaps she should ask them. He says that he did not grow the hair but whichever way nature made him it stayed that way, also that cutting hair can sometimes cause imbalances...... Sadhguru tells that once people on spirtual path let's say (brahmacharis) reach certain stage with their energies they are looking how to contain it and do not cut the hair because even a small disturbance can be felt strongly.
