Maharshi Kashyapa was the son of Mareechi. Daksha Prajapati married his thirteen daughters with sage Kashyapa. The names of those daughters were Aditi, Diti, Danu, Kala, Danayu, Sinhika, Krodha, Pradha, Vishwa, Vinata, Kapila, Manu and Kadru,

All these women gave birth to so many children that the whole creation was filled up with their progenies and off springs.

Aditi was the mother of all the Devtas and the twelve Aaditya (suns). Diti gave birth to the 'Daitya' (demons), Danu was the mother of the 'Danavas' (demons), 'Kala' and 'Danayu' also gave birth to the Danavas (demons) 'Sinhika' gave birth to lions and tigers, 'Krodha' was the mother of the demons who had great anger, 'Vinata' gave birth to 'Garuda', 'Arun' etc. Kadru was the mother of snakes and cobras and 'Manu' was the mother of all human beings.

Hence, it becomes quite clear that all the species which exist in this world originate from the same ancestor and hence all of us are like brothers and sisters. We are the offspring of Maharshi Kashyapa and so are the trees, the animals, the birds etc.

Out of these 13 women, Aditi was the senior most loving wife of the sage Kashyapa. She was the mother of all the deities including 'Indra'. Even Lord Vishnu incarnated as Vamana in this family. Lord Vishnu loves both Kashyapa and Aditi very much as the sage was a great devotee of Lord Vishnu. Lord Vishnu took three incarnations in the family of Kashyapa and Aditi. Due to their extreme devotion, the supreme Lord has manifested himself in the various incarnations and had taken birth in their family.

So, the credit of giving an opportunity to human kind to experience the supreme Lord by his senses who is reality is beyond any qualities goes to Maharshi Kashyapa.
