In the marketplace of the holy name, the most valuable commodity is faith; not material wealth, which is most valuable to mundane investors. But the analogy works in the same way. An investor who wishes to invest his wealth looks for a solid investment which will hopefully give him a good return. In the same way, one who has some faith in pure devotional service and the holy names, but also wants to increase it, has to be willing to invest his/ her faith in that person who invokes faith in pure devotional service and the pure holy names. The more faith invested, if it’s a genuinely solid investment, the more we’ll get in return.
