Let noble thoughts come to all from all sides!

Aano bhadra krtavo yantu vishwatah
This means "Let noble thoughts come to all from all sides".
This verse is from the Rig Veda, and has also been adopted by the Bharatiya Vidya Bhavan
as its motto.Hindu scriptures are full of such gems-simple statements driving home a profound truth.It is obvious that we must gather noble thoughts, so what's so great about this verse?

Here's my interpretation:
Let's take our epics for example.In the Mahabharata, the heroes are the Pandavas and the Kauravas are the villains. Similarly, in the Ramayana, Rama is the hero and Ravana, the villain.
Both these historical accounts describe the victory of good over evil-nothing seemingly special about this as there are countless stories across the world which talk about the victory of good over evil.

However, the standards of "good" and "evil" in the Ramayana and Mahabharata are not so simple. If we take SOME mortal characters in these epics, we can see that they had both good and bad sides to their personalities.

In the Ramayana, Ravana kidnapped mother Sita and also kept a lot of people as captives in Lanka, and thus became a sinner. Hence, he got what he deserved.
However, there is another side to him. He was a very devout Siva Bhakta. Indeed, the ShivataandavaStotram composed by him is one of the most moving hymns to Lord Siva.
Here, we need to appreciate his Bhakti while rejecting his anti-Dharmic activities.

In the Mahabharata, Yudhistira is described as the virtuous son of Yama, the Dharmaraja,
and an icon of rightousness.However, even he committed a grave mistake-he had no business to gamble his wife with the Kauravas after he lost everything else.
What we need to learn from his character is only his positive side.

Now, we can relate this with the Rig Vedic verse mentioned above-
We need to accept good thoughts-no matter where they come from.
It is interesting to note that in the magnum-opus Arthashastra, the great Chanakya
starts with salutations to both Dakshinaamoorthy (The Guru of the Devas) and Sukrachaarya (The Guru of the Asuras)- implying that one must imbibe good ideas from everywhere.
