I am making SMS categorizer. For this I want to classify my messages into different topics. So I want to use gensim for that. Can anybody provide me the source of any tutorial that can help me to begin topic modelling using gensim?

Radim Řehůřek, the author of gensim, provides tutorials on his website, which I found quite helpful: https://radimrehurek.com/gensim/tutorial.html
He also provides some tutorials on his github that are not that easy to find, so digging for a while in there might bring some great notebooks to the surface. For example, these two (for LDA): https://github.com/RaRe-Technologies/gensim/blob/develop/docs/notebooks/lda_training_tips.ipynb
https://github.com/RaRe-Technologies/gensim/blob/develop/docs/notebooks/topic_methods.ipynb
I personally found it very thrilling to start with the English Wikipedia, for which Řehůřek also provides a tutorial. Even though it takes quite a long time to train the model, you will find yourself with very "natural" seeming topics, which make it easy to test gensim's functionality.
