devotees. In worshipping forefathers and demigods, he should offer them garlands from the Deity of Lord Krsna. If, on the other hand, the householder devotee performs the sraddha ceremony according to the mayavadi's methods, or he worships other demigods, then he commits a heinous offense. To impose some dualistic concept on the Supreme Lord Visnu is a namaparadha and disqualifies one from the path of pure bhakti.

"A serious namaparadha is to consider demigods like Lord Siva to be separate supreme divinities. Polytheism is a grievous offense. Lord Visnu is the Supreme Godhead, but Lord Siva and the other demigods are also individually supreme1; this idea is incorrect: One can, however, worship the demigods as guna- avataras-, sakyavesa-avataras or as Lord Visnu's servants. No one is independent of the Supreme Lord's control, for He is the Supreme Controller and master of all energies.

You have no beginning, nor will you have an end. The material body will cease existing, but you will never cease existing.

Demigods like Lord Siva, Lord Brahma, Lord Ganesa, or the sun-god have been invested with, the Supreme Lord's potencies. Hence, they are powerful.The Supreme Lord is one; the rest are His energies. The householder devotee should abandon outright all materialism in the execution of his duties; he should increase his mood of pure devotion.

"Human society should conduct life according to the edicts of the varnasrama system; such a lifestyle is called sanatana-dharma or eternal religion. India is the land of piety (punyabhumi), and the varnasrama religious system was introduced and implemented here by great sages of yore. In other countries this system is also present in some form, though it never evolved into the perfected socio-religious system that was seen in India. Human nature cannot find full expression nor attain consummation without the social divisions of varna. To be sure, the eternal truth is this: like anyone else, even the low-born outcastes are fully eligible to enter the family of Krsna's devotees if they live their lives free from sin and offenses. Still, human society as a whole can neither properly exist nor function without the varnasrama system.
