How to do donations in a right way :
First of all analyse how much you want to donate every month selflessly without any intentions.

1) If you want to donate money then first of all find a temple which need money for construction, or old need renovation, Need water cooler

Or place where devootes can place their shoes or chappal or plant trees in temple. If you are done temple construction donations then keep on donating money for monthly Langar, or Food items rice Bag, Salt, Mustard oil, Wheat bag etc personally in temple.

Do not blindly donate in charity always donate things personally in temple.

2) For Major days like Amavasya and Poornima always donate Food items like Rice, Wheat, oil, pulses, Salt, Sugar to individual personally who is in need.look for the person who is in need.

3) Arrange Langar out of your income you want to contribute in the temple or gurdwara whom you have strong liking & Devotions, get prepare the food and personally serve all foods to devotees who are coming for Darshan

& also donate your food personally to those people who are around the temple are poor, Hungry or physically disabled.

4) Donate water Cans in temple or in Gurudwara in summer or also arrange Shabeel ( popular in Dogra & punjab culture), Water made of milk & Sweet ingredients

To all the people who are thirsty.Serve them personally.

5) Arrange cleaning in temple or gurudwara personally by your own hands on Sundays or Saturdays or whatever days you can perform and do it by your own hands.

6) if you are donating Food items as per Graha devta on varas then donate to that brahmin who is worthy and very learned, doesn't have any greed for anything.

7) Donate your blood volunteraly in blood donations camps.
