The song that I came to sing remains unsung to this day.
I have spent my days in stringing and in unstringing my instrument.
The time has not come true, the words have not been rightly set;
only there is the agony of wishing in my heart.
The blossom has not opened; only the wind is sighing by.
I have not seen his face, nor have I listened to his voice;
only I have heard his gentle footsteps from the road before my house.
The livelong day has passed in spreading his seat on the floor;
but the lamp has not been lit and I cannot ask him into my house.
I live in the hope of meeting with him; but this meeting is not yet.
Ka lawm e.

Pu Donald: Ni mai e, physical parameter nei lo chuan energy a nei ngai lo. Bible pawh hi fimkhur taka thlir a ngai thin reng a ni, science thiamna eng hmanga thlir hian diklo pui pui hi a awm nual a, chuvang chuan tih hlek loh a tha.
I sawi ang khian Thlarau chungchang hi Science hian a sawifiah ngai lo, a theih miah loh a ni. Thlarau energy anga ngaih phei chu a nuihzatthlak lutuk. A thiam ho bulah phei chuan sawi chhin eih loh tur a ni.
