There are four Yugas; time is divided into four aspects.
1. Satya Yuga, when there is a lot of positivity
2. Treta Yuga, when the positivity goes a little down
3. Dvapara Yuga, when the positivity goes a little more down, and
4. Kali Yuga, when positivity goes down even more
This is what is said about Kali Yuga. But I tell you, within Kali Yuga there is Satya Yuga.
The days when you feel happy, know that you are in Satya Yuga. And when you are totally miserable, you are in Kali Yuga.
In that sense, within the big Kali Yuga also, there are good times.
