hi swami,
there are umpteen threads here moaning the non availability of tambram girls. for various reasons, which if you peruse the threads, you will pick up the points of discussion, analysis, name calling, putting the blame and above all a summary of the stark reality.
you may have to accept the fact that there are no tambram girls available for you, and then consider the alternatives - either a life of bachelorhood, or looking beyond tambrams. if it be the latter, what is your comfort group - other tamil groups who may be vegetarian or any such preference, brahmins from other states (no guarantee that the girls here are willing to marry a 38 year old tambram either).
i agree that this is quite a jolt for guys and their parents, many of whom expected to repeat their own experience of 30 or 40 years ago, when girls lined up and boys could be the 'kings'.
there is another thread, about namboothri priests of kerala, who faced with the same problem,went to the orphanages and picked brides from there. the advantage, is that there is no in-laws to worry about. the girl, can be expected to 'adjust', though we should remember that she is a human first, and not a chattel.
best wishes to you swami, and may you find a mate soon. i do not believe any more in the old adage, that there is a girl for every guy. but in your case, i hope it comes true.
