Connections between Crow, No Moon, physical and spiritual realm in Tamil/Indian culture

Crow is the most intelligent bird. It needs respect all the time not just during Amavasya (no moon day).

1. Tamil tradition, the crow is considered a messenger between the living and the dead. It is a beautiful love of the living family members, by offering food, ensure that the ancestors are well-fed and satisfied in the afterlife. In folklore, it is often associated with the ability to navigate between different worlds, making it an appropriate intermediary for communicating with the spirits of the deceased. The black color of crows, akin to the darkness of Amavasya night, symbolizes the connection between the living and the departed. 

2. During Aadi Amavasya, barriers between the physical world and the spiritual world are thinner, making it easier to communicate with the souls of the departed.  The darkness of the night is seen as a symbol of the unseen world, where ancestors reside. This makes it an ideal time to offer prayers and rituals to seek their blessings and ensure their peace in the afterlife. The dark night of Amavasya, devoid of moonlight, represents the mystery and the unknown, much like death itself. Absence of the moon enhances the connection between the physical world and the spiritual realm. 

In science, during the summer earth is far away from sun (in Thai Amavasya, Jan-Feb, in winter earth is closer the sun). So, space distance does not matter but love distance to the ancestor matter.

3. The question is not whether the soul scientifically exists; it is better if the soul exists, rather than being soulless beings.
