This is a great time to be satisfied with what we have instead of desiring for more and more and more. Being satisfied with what we have leads to contentment, peace and happiness, while greed for more and more is like drinking salty water - the thirst only increases. Our basic needs are small, everything more than that is a luxury, so why not being happy with what we already have and using it well.
Greed might is much deeper rooted sickness of humanity than the present virus. Some people get into huge debts, many people do not plan their spendings, the majority of people have no emergency funds. In these times when people are shopping online, buying more often than needed burdens the postal systems - we can refrain from it also by considering the postmen. There are many ways to practice dharma in these days. The trend of minimalism has been consistently growing through the past years. It has been partially linked to environmental concerns and partially to larger social context and consequences of consumerism, including fair trade and other factors, which is great. Buddhist approach can include it, but it has a larger scope and different emphasis, as I understand it. It includes more than one life, all sentient beings and well-defined interconnectivity, yet its emphasis is not as much on what others or government are doing as on what we ourselves are doing. Primarily it offers mind training.
Our mind is the root from which our words and actions are arising. Classical example: if a poisonous plant is growing on our garden, we can remove the leaves, but the plant will continue to grow, but if we remove the root, we have overcome the problem. Being satisfied with what we have and gratitude for it can be a profound practice when we take it to heart. It is even deeper when we think how to use it for the benefit of all.
