I want to know the answer to the following question:
What aspect of Vaishnava was unpalatable for the Pasupatas?
All the background I'm provided with is that "Pashupatas disapproved of Vaishnava theology, known for its doctrine servitude of souls to the Supreme Being, on the grounds that dependence upon anything could not be the means of cessation of pain and other desired ends.". Is that enough to answer the question?
Answer: yes
