Bhagavan is a name of Krishna meaning "He who possesses an infinite supply of opulences." One of Krishna's opulences is wealth; whatever wealth we have is on loan from God and meant to be used in His service. How we think about and use money affects not only our ability to lead happy, harmonious lives, but also our ability to see ourselves in relation to Krishna, the Supreme Person and the ultimate source of all wealth.
The more we use our borrowed wealth in Krishna's service—in other words, in harmony with the supreme will—the more we become free of anxieties arising from greed and fear of loss. Krishna assures us of fearlessness if we surrender to His will, and how we manage our finances is symptomatic of our faith in Krishna's ability to maintain us.
