Buddhism is the abbreviation of Buddhism, which mainly has three factors: belief, will and action. Buddha is a teacher, a person who teaches truth, methods and answers doubts. He has been teaching people how to live and how to get happiness from suffering all his life. His theory is simple, not complicated at all. If you use these methods and principles to face all kinds of troubles, you will not be troubled and confused.
The biggest distress in life is as follows: birth and death. The Buddha taught us how to recognize these pains and find solutions. Today, Buddhism has evolved into at least the following forms: first, religious Buddhism, second, academic Buddhism, third, superstitious Buddhism, fourth, artistic Buddhism, fifth, commercial Buddhism, sixth, magical Buddhism, and seventh, educational Buddhism. On his deathbed, the Buddha predicted that in the last days of France, evil teachers would say things like Ganges sand. There are very few Buddhist disciples who really show their education now. No wonder many people are biased against Buddhism.
In your account, you mentioned that frequent visits to Buddhist temples can improve the diseases of the elderly. This is a phenomenon, seemingly accidental, but actually inevitable. Most of people's diseases come from troubles and habits. I often go to monasteries, where the environment is generally quiet and solemn, temporarily blocking people's troubles and habits, and the healthy qi of the human body can be continued. Over time, it is naturally conducive to the improvement of the disease.
However, not all people often go to temples, because Buddhism smells terrible! It is not easy to get in touch with Buddhism in life! A person who has no connection with Buddhism, even if you move his family to a temple, he can't hear Buddhism. If he is forced to learn Buddhism, he will not be able to do it, but will increase his troubles, and even let him vilify Buddhism and laws, which will only increase his bad karma. All this seems strange, but the reason is very simple. It's all caused by karma.
Our relatives, if there is such a situation, we can make a vow to do merit in return for these relatives. When their karma is eliminated and they listen to Buddhism, they will be happy to be trustworthy.
As a junior, believing in Buddhism first is a blessing accumulated by three generations, so we must cherish it. It is necessary to break evil and cultivate good, and set a good example for relatives who can't accept Buddhism at home. With our own examples, let them witness the extraordinary victory of Buddhism, thus building up confidence.
Buddhism is not difficult, but it is difficult to establish faith. When the letter is written, the next vows and practice will follow.
I wish your family a healthy life at an early date!
