My thesis advisor is absent in my final stage of completing my Ph.D. programme
You are about to finish a PhD thesis. Somebody who obtained a PhD title is supposed to be able to organize and conduct reasonable projects independently. I think that your adviser is not being unreasonable in his demands.

Part of organization is also arranging to get more time, if your current time frame cannot be kept, or leads to serious degradation in quality and rigorousness. In some cases that might lead to working on your thesis without being funded. Personally, I would still advise to value doing a good job higher than meeting a deadline, but of course I cannot oversee all the consequences.
