I believe the ultimate source of blessings is within us. A good motivation and honesty bring self-confidence , which attracts the trust and respect of others. Therefore the real source of blessings is in our own mind.
Material objects give rise to physical happiness, while spiritual development gives rise to mental happiness. Since we experience both physical and mental happiness, we need both material and spiritual development. This is why, for our own good and that of society we need to balance material progress with inner development.
