I've learnt that certain vegetables are avoided (Onion, Garlic, beetroot etc) on Shraddham/Tharpanam days for 2 reasons:
- They are Aphrodisiac in nature.
- They are grown under the land.
Can someone explain, what is the story or what is the significance of the second point?
Or like, why should we avoid foods that are grown under the land? Any specific spiritual reason, or Pauranic story?
Please let me know.
