ABSTRACT
Since time immemorial, the Simte Communitarian way of life has been perpetuated and sustained by the unique social-ethical principle known as tawmngaihna. It is the principle or practice of concern for welfare of others. This principle is called tlawmngaina in Mizo and Hmar; the same word is also used among the Paites, Gangtes, Vaipheis and Thadous and also called sobaliba in Ao (Naga). A tawmngai person is honoured greatly for being motivated and encouraged by the community. But in present society, though the still exists in different ways, it has become weaker in practice. In order to have strong social force as in past which protects the poor, needy and weak, maintain social harmony and equality, ready to help in time of distress, it is important to preserve and promote this basic philosophy within the community. So far, it is not realize and appreciate the value of such selfless culture or virtue of selflessness which is declining slowly with time.
