I'm sure TNH is a truly wonderful person and obviously far more advanced than myself -and I do understand this approach ....but it also seems very romantic and unrealistic. It appears to me that one needs to be a fairly advanced practitioner to have the penetrating awareness that encompasses a deeper non-emotional understanding of another person and their needs
but that's not really compassion, its emotional attachment. Indeed personal suffering of that nature is the kind which surely we need to understand and overcome whilst still having the ability to empathise with others.
