With a gentle smile Mahaswamigal answered, we call crow kaka in Tamil. Do we address any other creature by its sound? Do we call cat meow? Because a parrot says kiki, do we call it kiki? The crow is called by its sound that makes it special.
Ka means kaapathu or protect me in Tamil. so when you keep food for a crow and say "kaa kaa", you are asking your ancestors to protect you!
You say a crow is lowly because it is freely available and it eats anything! But let me tell you a crow is beautiful. Why?
It wakes up at brahma muhurtham.i.e, 4:00 AM. It caws and wakes you up. Even cocks may not wake up on time many days as they are moody, but a crow is on time. It says "kaka" and wakes you up at Brahma Muhurth apt to do Japam. It is such an amazing guide for pooja no?
Further, it calls other crows when it gets food, not seen in other creatures, teaching humans to share their food. Then in the evening before it sleeps, it again says "kaka" to thank God for all that happened that day!
Also crows don't eat after sunset which is according to shastras. How many people follow this?
Hence, I feel a crow is not lowly. It teaches us so much. Hence pitrus come as crows.
And one more keep food for crows everyday not only during mahalaya.
Crow also teaches #Advaitam
When a crow sees the food you have kept, it gets happy and eats it. Seeing it eat you get happy too. So both of you get happy both are Bhagawan! Are our sages mad? Why did they made us feed crows, if we have to give it to our ancestors?
The sages had strategic consideration.
This is the real reason -
Have you grown a peepal or banyan tree someday?
Have you seen anyone grow it?
Can you get seeds of peepal or banyan tree?
The answer is no.
Peepal or banyan tree will not grow out of #sapling
Because nature has arranged a separate arrangement for growing these two useful trees.
The seeds sprout only after they have been processed in their gastrointestinal tract of the crows. These tree grows wherever the crows eat it and wherever it does its excretion.
Peepal are the only tree in the world that releases oxygen round the clock and the medicinal qualities of Banyan is also immense.
If these two trees have to survive, it is not possible without the help of crows.
It is in this period, crows do mating. To get healthy new generation of crows, they needs to get healthy food. Hence our ancestors made a ritual to feed the crows.
Next time you see peepal or banyan tree or a crow remember our intention of our ancestors.
