Volunteers are not mere workers.
A worker could be good at working, but not at planning or decision-making. Similarly, the planners and decision-makers could be good at their jobs, but not at executing them. They are specialists, whereas volunteers are all-rounder. They are good as workers, as executioners, as planners, as decision makers, as initiators, and as leaders.
Volunteers work without any personal motivation. They work to benefit others, not themselves. This makes them workers par excellence, executioners and leader par excellence. The Volunteer Dharma, therefore, is dharma par excellence.
To volunteer is to live in accordance with dharma in accordance with the values of righteousness, selflessness, and above all egolessness. To volunteer is to practice humbleness; to volunteer is to live in synchronicity with Mother Nature, loving, caring, and sharing as She does.
A Volunteer is essentially a Spiritual Practitioner, a Sadhaka, a Karma Yogi one who is striving for the ultimate union with the Supreme through selfless action. Blessed, indeed, are all of you, engaged in this holy work.
