No. That is not correct. Guru destroys karma. The guru does not take the karma of the disciple onto themselves. That is not our scripture. This is wrong and artificial thinking. An artificial matter. This is wrong Gaudiya siddhanta.
Diksha destroys karma. Take shelter of hari-nam. Hari-nam can destroy at once millions of karma. Pray to Hari-nam. Take shelter of Hari-nam. Hari-nam is very powerful. Hari-nam is very merciful. Hari-nam will advise you; your mind, knowledge and onto the pure devotional path.
