Karmaṇā, by our act. Janmaiśvarya-śruta-śrī (SB 1.8.26). By pious activities, one can get these four things: birth in high family, rich family, brāhmaṇa family, cultured family, janma; aiśvarya—riches, opulence; śruta—education; and śrī—beauty.
So I say to my American and European disciples always that your nation, American nation, you have got your birth in a very rich nation or rich family. In America, every family is rich because there the poorest man earns monthly not less than four to five thousand of rupees, according to our (indistinct). The poorest man. And what to speak of the richest man. So janma, aiśvarya, śruta, śrī, these things are achieved out of pious activities. Therefore, in the Vedas, the karma-kāṇḍa vicāra, performing great sacrifices, they are mentioned. (Sanskrit) Performing yajña. In order to keep ourself happy within this material world, we have to perform yajña. That we are forgetting. There is no yajña performance.
