Money Gift : Zero at the end is not considered good
Sanskrit saying, ‘two persons constituting a mission is good, but the two should not be the father and the son; nor should the two be two brothers. It is, neither, auspicious for nine women to go in a group, nor for three Brahmans to constitute a delegation of three.’ Brahman is a priestly caste. What is the rationale behind the above dicta? We do not know who laid down the above dicta. But these rules are being followed to this day.
While giving presents, 1 is considered auspicious; 2, more auspicious than 1. But 3 are considered inauspicious. You may give 1 rupee or 2 rupees as a gift or presentation but never 3 rupees. 4 are generally avoided, though it is not considered as bad as 3. 5 are considered good. One never makes a present of 6, 8, or 9 rupees. 7 are considered good.
While giving a present at a marriage or some auspicious occasion, a number ending in 0 is avoided. We present 11, 21, 51, or 101 rupees but not 10, 20, 50, or 100 rupees. Suppose you have to make a present of 200 rupees, you should present 201, because a zero at the end is not considered good.
Hindu scriptures law down that a complete reading of Shrimad Bhagavatam 9a holy book) should be performed in seven in seven days exactly. Number 7 is in special harmony with the sacred scripture, Shrimad Bhagavatam. But if you have to recite the Ramayana (another sacred book of the Hindus), do it in nine days; neither 8 nor 10 because number 9 is in harmony with the Ramayana. Shrimad Bhagavatam has 12 chapters. Since chapter 10 is very long, the other has divided it into two parts instead of splitting it into 2 chapters. Had he done the latter, the total numbers of chapter would have become 13, a number not in harmony with Shrimad Bhagavatam. This shows that the Hindus had a deep applying it to practical life.
