The question what will happen when we donate dress to poor on Amavasya was asked by a reader. Donation and charity performed at any time and day is highly meritorious as per Hinduism.
As per astrologers donating dress on Amavasya will help in attaining peace and prosperity. It will also help in early cure to long term diseases.
The best charity is that which is performed without thinking about the fruit of it. Do not wait for ill luck or diseases to perform charity. Do little bit you can whenever possible.
