Now there should be examination whether so-called brahmanas, they are actually following the brahmana regulative principle and chanting the mantra regularly. Otherwise they should be converted again sudra. If we become safe simply by having a thread and do not do properly, then what is this? This should be examined. Every individual should be asked, "Now chant this Gayatri-mantra." He must.
Are they doing properly? Then it is all right. Otherwise, simply by name, so-called sacred thread holder will not do. Then again the same brahminical class as in India.
