Deity worship is essential for householders

An opulent householder devotee who does not engage his hard-earned money in the service of the Lord is called a miser. One should not engage paid brahmanas to worship the Deity. If one does not personally worship the Deity but engages paid servants instead, he is considered lazy, and his worship of the Deity is called artificial. An opulent householder can collect luxurious paraphernalia for Deity worship, and consequently for householder devotees the worship of the Deity is compulsory. In our Krishna consciousness movement there are brahmacaris, grhasthas, vanaprasthas and sannyasis, but the Deity worship in the temple should be performed especially by the householders. The brahmacaris can go with the sannyasis to preach, and the vanaprasthas should prepare themselves for the next status of renounced life, sannyasa. Grhastha devotees, however, are generally engaged in material activities, and therefore if they do not take to Deity worship, their falling down is positively assured.
