Can the principles of bhakti solve the world’s practical problems?

So do the principles of Krishna Bhakti have they helped me to solve any practical problems in the world or any practical issues people who are not practicing spirituality also they face before I was introduced to Krishna Bhakti I was involved with a social service organization a social welfare organization and as a part of that organization I would go to a nearby slum like a ghetto area near my college and there I would I would teach like free tuitions for the kids over there so I had a lot of faith since my childhood not childhood teenage years in the power of education in bringing about change so when I would go to these slums I teach I used to teach English, mathematics, history so many of these children opened up and they were from dysfunctional families most of their fathers were alcoholics and there's domestic violence so I started thinking at that time how much can this knowledge really help them their whole life is a mess so our organization decided to go into anti-alcohol campaigning and then we got some de-addiction experts on board and we used to give talks on that so one of my friends he adopted a nearby village and we made that whole village free from alcohol got everybody to stop drinking and that was considered a big success for us but then one day after that my friend came and he came back I had gone to this slum nearby he had gone to the village he came back in the evening and he's crestfallen I asked him what happened he said the previous weekend in the previous week there had been the local elections and the candidate over there in order to get votes he had brought two truckloads of free liquor for everyone and not only the fathers but even their kids are drunk so then at that time it was very disheartening at one level but also it was eye-opening I felt that as I said I had faith in the power of education that education opens doors for people education provides options for people which they would not have otherwise but then I realized that we don't just need to open doors and provide options we also need to give people some inspiration some motivation some willpower by which they will walk through the open doors so otherwise people can ruin their lives so in my college itself there was there was one student who was in the final year of engineering when I was in my first second years and he was a brilliant student he'd been a topper throughout number one in the university and he was also a chain smoker and he got at that time the highest paying job in the history of our college it's considered a big success but then within the first six months of his having a job he was detected with advanced lung cancer and he died so it struck me that here you could say these the parents of these children in slums they were uneducated and they were alcoholics but here I could see a student he was in one of the top universities in the country and he was one of the top students there even he destroyed himself so just education there's no guarantee that a person will get the intelligence to make to use wisely the options that are open for one so I felt that if we can provide some knowledge by which the people can be empowered to make good choices now both when I would meet these alcoholic parents alcoholic fathers you know when I would talk with them they were nice people they were not like arrogant or brutal or insensitive not monsters they were there when I would go and talk I would give classes for their kids they would be grateful they would thank me for coming there so but their mothers or these kids would tell that when they would drink they would become like another person so even this boy who became a chain smoker he was a very intelligent guy but smoking was like an irrationality within him so it destroyed him so at that time I felt that we also education opens doors but there is something inside us which sabotages us and we need protection from that we need the inner vigilance by which we can walk through the doors that are open for us and that education to be internally vigilant that is what I felt Bhagavad Gita gives and as I said earlier also how one of my close friends was on the path to becoming an alcoholic this became transformed and I have seen that a lot of people in different parts of the world when they start practicing spirituality and start practicing the Bhagavad Gita's principles they do change they are able to break free from self-destructive habits and they are able to live more productive lives even at the material level so spirituality will take us to a spiritual destination ultimately but spiritual growth can also help us to contribute better material which you would not be able to do otherwise so in that sense what the Bhagavad Gita offers us is spiritual humanism the people talk about secular humanism where humanity is the center should work well for the human beings but you can have a spiritual humanism also where there's a spiritual vision of human beings and spirituality helps human beings to become better human beings so that way Henry David Thoreau he said that one hacking at the root of evil is more effective than a thousand hackings at the shoots of evil so we have so many problems in the world today but if we say one hacking at the root of evil say for example there is sexual violence sexual assault that's primarily because of lust so if lust could be controlled then that would decrease there is so much corruption there can be specific causes for it there's so many scandals which happen but the fundamental cause of that is greed so lust, greed, anger they cause so much human misery and spirituality is a process by which these root causes of the specific problems that we face in society they are dealt with so when we become spiritual we are hacking at the root of evil and once we hack at the root of evil then we will find that the shoots will automatically fall so if people became more spiritual they would become less wildly driven by anger less wildly driven by greed less wildly driven by lust less wildly driven by envy and they would become better human beings and that would contribute substantially to solving the problems that we see in the world today okay, thank you.
