Tom: it varies. Here in the UK there are quite a lot of neo-advaita teachers and being UK based myself, over the years I have dealt with many people who have been very traumatised by these teachings and I have guided them through the process of undoing many of the false concepts and beliefs present in neo-advaita teachings.
The neo-advaita ‘non-teachings’ can be very abrupt and triggering and not leave (apparent) people with any sense of agency or empowerment to deal with the consequences.
I have seen near psychotic breakdowns, severe anxiety and panic disorder, depersonalisation and derealisation, relationships fall apart, people losing their jobs, lots of confusion and disorientation, depression…
In my experience Neo-advaita tends to be a feel-good teaching in the moment for those it helps, and mainly is for the intellect.
It feels good in the moment but the sense of duality and confusion keeps on returning, and it doesn’t lead to a genuine realisation of truth or love. When one engages with genuine self-enquiry we come to see just how superficial the neo-advaita teachings are
Neo-Advaita is actually far away from the true teachings even though some of the words sound similar. In some ways neo-advaita is more intellectually coherent than true Advaita teachings, but that doesn’t make it true or effective.
In my experience the true teachings, such as the teachings of Sri Ramana Maharshi, guide us directly and unfailingly to realisation, the shortest route so to speak, with the minimal amount of suffering along the way.
