dahal ji, I am impressed with your love towards your elders. God bless you. With this, I am contributing my time to write some suggestions. Hope this helps.

As rahulvai has said, you don't know her requirements and thing that you buy may not mean much to her.

I have bought some goods which I thought would be great for my parents but they were not (Iphone - excellent gift as I throught but they never used it). I am going to Nepal soon and asked my mom what she need. Her answer - what can be better gift than that you yourself is coming.

My suggestions:

1. Call her regularly, ask about her health, ask what she eats, ask is there is someone to help her - that mean more than anything and you will also know what she uses or eats most
2. If possible, go to Nepal and visit her. Assuming that your hajurama lives in Chitwan (just assumption), hire a car and take her to Devghat for a comfortable trip. I did this to my grandmother and she always remeber this.
3. Ask what she eats. Send $100 cash so she can use this money to buy fruits, milk etc. We think $100 is nothing but it seriously make difference for them.
4. Send any small gift. I gave a nail cutter to my hajurama. This cost me just $2.5 but was so much for her. It's not important what you give....it's important that you remembered her.
5. Along with $100 send extra $20-30 to your mom asking to buy a dhoti/saree or sandel for your hajurama. Your mom knows exactly what to buy for her.

Once again. thanks for remebering your elders...many of us forget to remeber them and don't send things thinking we do not have money now. Remeber, it doesn't matter what you send....main thing is your remebered them.
