Pooja, like I said.. from what I know, and what I've read, a haiku usually does not rhyme. There was no usage of rhyme by the masters in Japan. I've read haiku from a lot of time, and yes, when translated the rules from Japanese tradition to English, there are places we do compromise.
Take for e.g. the syllable count. Haiku in its originality has 5-7-5 ON. ON is Japanese syllables. In translating to English, it might be even less than 17. sometimes, it becomes 18 too, but in general, we keep it to a maximum of 17 syllables... I've written haiku which are 3-5-3, 5-6-6, and even random formats, but keeping syllables under 17.
Similarly, in keeping to what I know of, I told that rhyme is not there in a haiku. If you are wanting to put rhyme into a haiku, I wouldn't consider it as a haiku. Even at HH, multiple times, people have given in rhyming haiku, and ones which are above 17 syllables. I've told them what I know and feel to be.. some accept, some don't. I can't force a view, right?
To read a haiku.. well, a haiku is of two concepts split by a kire. so it can be read as two parts.. and when it is 3 lines, they can be taken individually too. It makes sense.. it has depth.. and one of my teachers herself told, when you are truly rhyming, that depth is not understood. That is another reason why I feel the greats like Basho etc.. their haiku had also no rhyme...
I agree with Sonia.. Shashi sir does know a lot about haiku... and in a few of his, I've seen rhyme.. internal like what you had. It is just what I know, the points.. the ones I keep for HH and ask my wonderful friends who share there, to keep too.
