Time takes care of many things – Although this man (SK) is deceased, there are dark aspects that some of His successors are still promulgating in his name.
The safest, surest and most complete path in its purest form set up by the Master is Self-Realization Fellowship/ Yogoda Sat Sangha(India). Follow SRF path and you will be ok!
