Frankly, at this present times, which Buddhist organizations runs well and 'survive' with donations only. None that I see. Even if it is by donations, how much has they grown in size and how much has they reached out to. Am not criticizing but more importantly, not to have an empty cold centre. Thus, various creative means is necessary to sought for to help sustain the organization for the benefit of many be it the staff or volunteers and the people at large to be reached out.
Question: What is the purpose of a Buddhist organizations existence if not to help, guide and a place of learning and solace/refuge for others?
In addition, it also helps to serve many involved to learn and practise alongside what work or business that has been assigned to do. To view it as our means of practice and as retreat too. Not so much of business to earn profits but more so for sustainability of the organization for we still need to pay utilities, wages, rental, stocks, printing, etc. Or unless there is some form of funding from government or foundation available to subsidize the organization's sustainability goals other than the donations from members and public.
