THere is a saying, "The more you give, the more you receive" or "the more you give the more happy you are".
The principle of giving is true. Like sowing and reaping. Can you imagine a sack or rice palay seeds of 40 kilos can make up to 50 sacks of 40 kilos during harvest when properly maintained? That is also the principle of giving. The more you give, the more blessing you will receive.
Better to give because our heart makes us happy. Try it and you will know.
