the tantra temples of khajuraho in india is situated on the top of diamond mines.as i already wrote that diamond is connected with sex in hindu astrology.very interesting thing about diamond is that it is the only hardest metal on the earth and it vanisheses totally when heat up 768 degree celsious without leaving any ash or anything.,in spiritialty it is connected with truth which is eternal or which never changes as it never changes its form diamond also never changes its form . . and very mysteriously in ayurveda diamond bhasma is used for treating cancer.my understanding is that cancer is connected with past life karmas .so diamond ,tantra and cancer has deep connection.diamonds,tantra can be very helpful in treating cancer and healing the past life karmas.in old hindu scriptures there is stories about syamantak mani[ precious stone] which is connected with tantric krishna.in great hindu epic mahabharat krishna talks about playfullness. if you are here and now not thinking about future or PAST your life becomes a leela OR A GAME then you dont creat a karma. ,bhagwan krishnas message is very clear that if you are here and now you will not creat any karma.you become a vehicle for god .and then life becomes a leela or a game and if weare in our mind or in our ego we are creating more karmas.so connecting with krishna conciousness is necessary to avoid the karmas and to live playfully .modern world has become so serious because they dont practise tantra which brings playfullness in life. future belongs to tantra and all the problems of the world can be solved through tantra. i was reading scientist talking about global warming .my understanding is that global warming can be solved through tantra as we start celebrating our life existance also participate with us. in existance everything is interconnected so temperature will become harmonious. as now be are in anger ,hate ,vilence,terror, fear ,so the earth is also in chaos ,the temprature is in chaos. but as we start tantra and start celebrating our life earth will also respond with harmonising the temprature as in existance every thing is connected and each person is responsible for what so ever happening in the world right now. making efforts like pollution controll cant solve the problem. as whatever we are doing rightnow is an unaware act.tantra also brings awareness .so with awareness we can choose what is good for humanity and what is bad.what so ever modern days politicians are doing is wrong because they are unaware and unconcious. only a person having awareness knows what is right and what is wrong .because a aware personss third eye chakra is opend.and with the opening of third eye chakra awareness comes.tantra brings awareness ,compassion and harmony. i like politicians should we choosen on the basis of his awreness but not on other basis. a politician should be a tantric and a meditator. in india all the ancient kings like krishna ,rama ,all were tantrics and yogi and in their time humanity was its in golden age. with their wareness they serve the humanity best as they were aware and knowing what is right or wrong. they were not like modern days politicians who takes decision based on morality and conditionings or for their greed. so there will be peace ,harmony ,balanced temprature if we practise tantra.
