O mind, the doors of joy have opened! The entire house was drenched, and even the new blue sky became wet.

This beautiful couplet speaks of immense joy. It says that the doors of happiness have opened wide, drenching everything. Oh mind, it's as if your entire inner world, your "house", is soaked in this delightful feeling. Even the vast, new blue sky or perhaps a fresh, blue garment, is completely drenched. This suggests a joy so profound and pervasive that it not only fills your being but also extends to encompass everything around you, making every new experience vibrant and immersed in happiness. It's a feeling of complete contentment and bliss, washing over everything.
