I do not know what kind of standard there is in the gurukula which you are talking about. If the standard of education is high—at least comparable to the standards that most Russian children have—then, by all means, the gurukula is better than nondevotee schools. However, if the standard of education is low, then it is risky to send your daughter to such a school.Certainly, it is also a great risk for your daughter to be exposed to the association of nondevotee children in ordinary nondevotee schools. She will need a strong will and great support from her mother and father to withstand the pressure that she will get from her classmates. Some children have the willpower and strength to withstand it. However, some do not and they succumb to the pressures of their peers. There is no sure outcome by either route—gurukula or nondevotee school. You must use your discretion. But in the final outcome, you should want your daughter to want to be a devotee, and you should want your daughter to have a basic education.
