To facilitate refinement and transformation in human beings, God takes birth in human form from time to time. This refinement can be brought about by different methods at different periods in time. In Krita Yuga, the method was ‘Dhyana’, in Treta Yuga, the method was ‘Yajna’, in Dwapara Yuga, it was ‘Archana’ and in the Kali Yuga, the prominence is given to ‘Namasmarana’. These are the royal paths available to human beings for changing themselves. (SSB 1978, p. 8)
