The best thing for your wife is to try and tolerate the pains and to execute her devotional service to the best of her capacity. If this is difficult, then she should try to get the proper treatment for her problem. And in this case, you may consult with Jagadisa dasa for advice. Under any circumstances, she should follow all the rules and regulations and chant at least 16 good rounds daily.
Letter to Jitasvara dasa, 17 April, 1975
