You can't put much energy into giving when no-one's putting much energy into receiving. These days giving talks tends to be like this, and it's getting worse all the time. People don't search for truth, they study simply to find the necessary knowledge to make a living, raise families and look after themselves. They study for a livelihood. There may be some study of Dhamma, but not much.
Students nowadays have much more knowledge than students of previous times.
They have all the requisites at their disposal, everything is more convenient. But they also have a lot more confusion and suffering than before. Because they only look for the kind of knowledge used to make a living. Even the monks are like this. These are the words of someone who has completely cut off the path of practice.
