I have heard some people say that soul was very pure in Satyuga and eventually it became less pure, and in Kalyuga it became impure. This is complete non-sense. It is not like that.
In Satyuga also there were Rakshasas (demons) like Hiranyaksha and Hiranyakashipu, they would intervene every time someone prayed or took the name of God, and the Avtaras had to come four times to get rid of them from the Earth.
In every age, the soul is beyond time and is eternally pure. It is wrong to think that the soul has become impure.
Kaliyuga is also good. Don’t blame the time.
You have heard the saying, Kalyug Kewal Naam Adhara. Just by chanting the name of the Divine it is easy to attain God in Kalyuga. So don’t say Satyuga was better than Kalyuga.
Irrespective of the time, seekers have been doing sadhana and have attained the ultimate goal. So, you too can attain such perfection even today.
