My very dear one,
I am sorry it took a long time to reply. I checked and according to my observation both your children should take precious pills [Tibetan medicine].
The pills should not be exposed to the light, so that means they should be opened either in the dark or under a cloth. The pills come wrapped in a cloth, so another way of taking them is to put the pill straight into one's mouth after cutting through the cloth, to avoid exposing the pill to light. Bite the pill and swallow it with warm water. As your children are young and the pills are hard, you can crush them, but do that in darkness.
Then for the next seven months, do the middle-length Medicine Buddha puja each month. This can be dedicated strongly for you and your children. The main thing is for purification, not only disease, spirit harm, negative karma and defilements. Most importantly, it’s so we don’t have to be reborn in the lower realms, but have a high rebirth, meet the Dharma and achieve enlightenment. Doing Medicine Buddha practice is extremely good for all of you.
Also you should read Liberation in the Palm of your Hand, by Pabongka Rinpoche. Study it from beginning to end by reading it mindfully. This becomes a kind of meditation, especially relating it to your own life. Anything you don’t understand, you can write down the questions in another book and discuss with someone who has studied lamrim and philosophy extremely well, or you can send your questions to me. If I know I can try to answer, but it may take a long time.
This is so important, more important than anything else in your life.
With much love and prayers ...
