Investing in government sponsored mutual funds, inflation indexed bonds, govt securities etc is the 'safest' way to invest, albeit with lesser (but guaranteed) returns.
Excess focus on gold not only harms and has harmed the economy, but also is an unpredictable commodity as proven by the recent slowdown. Had i spent 3lak rupees to and bought gold 3 months ago as an investment, i'd be weeping right now. Real estate is also tricky, but the returns are greater.
One way to be relatively safe is if you buy property(flats/apartments, 2bhk etc) by reputed builders, JP, Amarpali, DLF etc, and of course while considering development of areas around it, most importantly to look out for a school and a hospital nearby,
Just my two cents
