Whatever Mao Zedong asserted and claimed was perfectly alright because he was 20th century great community leader of China.
We are in 21st century where due to natural science advancement even social science has also been moving forward rather than remain in the status quo like people mindset remain as it is because of the dogmatic sociopolitical theological related theories.
In Nepal and India we have layers of discrimination based on colour, class, caste, creed, and cult as well as biological sex and social construction of sex called Gender. However, in the western world and China, people have not faced and experienced discrimination like we do in India and Nepal. This is the reason WHY western world theories of Marx, Engles, Lenin and Stalin are not applicable all in one. However, it is applicable partly.
I love learning all types of theories but social science related theories I don't find useful in our day to day life because it is not applicable in changing time, place and social context. However, as asserted and claimed by Mao Zedong, a Chinese communist revolutionary who was the founder of the People's Republic of China, which he ruled as the chairman of the Chinese Communist Party from its establishment in 1949 it is not complete true but definitely it is partially true. He said, "The theory of Marx, Engels, Lenin and Stalin is universally applicable. We should regard it not as a dogma, but as a guide to action. Studying it is not merely a matter of learning terms and phrases but of learning Marxism-Leninism as the science of revolution. It is not just a matter of understanding the general laws derived by Marx, Engels, Lenin and Stalin from their extensive study of real life and revolutionary experience, but of studying their standpoint and method in examining and solving problems."

I find fascinating to learn and explore how people think and understand different issues from their own perception, level of consciousness, understanding and information and knowledge that they hold inside their brain. Most of the people talk about science without truly knowing what is science.
Usually Nepalese people think science is physics, chemistry and biology subjects. However, to learn and understand science first of all conscience is utmost important. If individual doesn't have conscience in their head it would be wise NOT to talk about science suffering from own sensory organs created illusion and delusion to spread rumors, myths and false information believing and clinging on fictional literature related knowledge and information. Even well educated professionals think that theories are science.
In fact, NOT theories are scientifically true and universal only those that are based on natural science. Social theories such as Marxism, Leninism, Feminism, and so forth can't be considered universal. But dogmatic people who can't think differently other than their loved dogma (ideological belief) whether that be theological dogma or sociopolitical dogma think and believe that whatever applicable in one time, place and social context is equally applicable in another time, place and social context. This is false belief and understanding of those people who can't think beyond their ideological dogma that has been swallowed without digestion thus love to be nauseated among others as well.
One of the facebookers in my above status pointed out quoting from the statement of Mao Zedong "but guide to action".
In response to him stating, "All socio-political-economic ideological belief that are considered social science theory/ies are no doubt is a Dogma whether its followers think and believe it is guide to action or not.Have a look in Nepal or even elsewhere hardly anyone want to change their way of thinking from different thoughts, ideas, ideological belief, theories, or else. Everyone thinks my way is highway and others are shit. This proves how dogmatic people are who cling on one set of principles or theory rather than strive to be a pragmatic adopting each and every bit of good from different thoughts, ideas, ideological belief or theories."
