Compare and examine. Go right ahead and do that. Look at both sides.
And as well as that just take note of the fact Srila Prabhupada wrote this:
AND
You find some differences between the teachings of Srila Sridhar Maharaj and Srila Prabhupada.
You will also find Srila Prabhupada wrote things that contradict what Srila Prabhupada wrote elsewhere:
"The conclusion is that no one falls from the spiritual world, or Vaikuntha planet, for it is the eternal abode" (Srimad-Bhagavatam 3.16.26, purport)
AND
"The original home of the living entity and the Supreme Personality of Godhead is the spiritual world. In the spiritual world both the Lord and the living entities live together very peacefully. Since the living entity remains engaged in the service of the Lord, they both share a blissful life in the spiritual world. However, when the living entity, misusing his tiny independence, wants to enjoy himself, he falls down into the material world." (Srimad-Bhagavatam 4.28.54, purport)
What are you supposed to think when you read this sort of anomoly?
Srila Sridhar Maharaj gave the example that in the beginning a child is told the earth moves around the sun and that the sun is stationary. Then when the child is more learned he is told that the sun is also moving inside a galaxy.
To give another example, in Bhagavad gita we see Krishna teaching different kinds of yogas and that Krishna says if you cannot follow the highest path then try to folllow an easier path:
According to a person's intelligence he will accept whatever path seems best to himself.
If you cannot follow one path youself, don't criticize the path. Realize that your intelligence is limited but that God's grace is unlimited and that through many Gurus the One God is revealing himself to humankind.
If you criticize a real Vaishnava such as Srila Sridhar Maharaj then you may end up suffering a similar fate to other people who attacked him such as Kirtananda, Bhavananda and Harikesa.
Do you want to end up as a mentally ill drug addict taking sedatives, like Satsvarupa? Satsvarupa wrote an article attacking Srila Sridhar Maharaj and some people imagined Satsvarupa's article was very clever and that he was a big scholar. But look and see the sort of person that Satsvarupa has become now! The man has to go to a psychiatrist to get counselling for his mental illness!
