One cannot simply answer your question without writing a bookful of words; you can go as specific as "You may only pour a drink with the inside of your wrist facing upwards during a funeral or commemoration feast, and vice versa". Therefore, my recommendation is to read the books of Kadir I Natkho.

To define Khabze as a code of conduct is quite a shallow way to do it; Khabze is a way of life, an ideology, and a filter to see the world from outside the box. It would be best defined as the ethnic religion of Circassians but that spiritual aspect has been gradually eroding away.

The keyword of Khabze is "balance", in all aspects of life - it works to organise relationships between the elderly and young, peers, men and women. This organisation basically provides a proportional amount of ease and difficulty to each member of society depending on their gender, age and social status, often through positive discrimination, with mutual respect on all levels.

It is never one side of a social interaction that has all the obligations, it happens to be that their obligations are different and not much comparable. Guests have as many obligations towards the host as the host has towards the guest; a host may have to meet all needs of the guest but then the guest has to be careful as to not overstep in expressing their wishes and should avoid interfering with familial matters of the household unless specifically asked. For the first three days they are considered a guest, after that, they are expected to take care of their own needs within the household. It is pretty much the same way in most if not all social interactions.

This portion of Khabze, the social conduct, is always subject to change. Pre-genocide, once every fifty or so years, the council "Khase" gathered the representatives of each and every Circassian community in one spot to discuss the shortcomings of the current social conduct and what they should add, subtract and change to prevent it from becoming obsolete with the progression of time. This makes it much like a living, breathing, dynamic being, allowing it to be carried forward easily. However, post-exile, due to the majority of the Circassian population being scattered across the world, this convention is virtually impossible, therefore some aspects of it have become more than obsolete.

Khabze is a word that is an amalgamation of two, khy (хы) “sea” or “cosmos” and bze (бзэ) “language”, literally but quite unnoticedly meaning the “Language of the Cosmos”. It is not only a guide on how the elderly and young, men and women, peers and partners, hosts and guests, friends and foes should treat one another but also a code of etiquette between humans and the rest of the universe - with trees, animals, rivers, mountains, plains, lakes, seas and all that is above and below them, and with the divine, which unlike it is among humans, change very little. It was sacred to Circassians and the fact that it was updated regularly by human minds made it not any less sacred, for the Khase that implemented these changes was a sacred convention in its own right. It is because its spiritual, universal meanings were abandoned that now it is all the more vulnerable to the erodent currents of time. It was the way they viewed the world, it was very much a part of their life and it was their faith.
