I’ve often struggled with the issue of social engagement, living the lay life, and making a living. In an attempt to get my head around this, I gave a talk at our local meditation center on the topic of leadership and work in the EBTs, and also tried to link it to modern work practices. The link to the slides is here: Buddhanusati: Reflecting on the leadership lessons of the arahants in the EBTs
Specifically, slide 35 includes the Vanaropa Sutta SN 1.47 which describes the importance of charity. I hope this is of some help.
