In a saucepan, bring the milk to a boil, keep stirring intermittently to prevent it from burning at the bottom. Once it comes to boil, reduce the heat and let it simmer for about 10 minutes. Remove the saucepan from the heat and set aside till it reaches room temperature. Refrigerate until further use.
Soak the sweet basil seeds in about 1 cup of water, stir it well, and set aside for 30 minutes. Once they swell, drain the excess water in a strainer and set aside.
To prepare the Falooda Sev: Heat water (about 125 ml) in a saucepan. Let it come to a boil. Once it has boiled, add the Falooda Sev, and let it cook for about 5 minutes. After 5 minutes drain the Falooda Sev using a strainer and transfer to a bowl of cold water, to stop the cooking process further. You can cut the cooked Falooda Sev in smaller pieces using kitchen scissors.
To assemble the Falooda: Take a tall glass, add about 2 tablespoons of the sweet basil seeds, 1 tablespoon of Falooda Sev, 1/4 cup of mango puree, 1 tablespoon mango pieces, pour the chilled and thickened milk, then another tablespoon of basil seeds and Falooda Sev each, 1/4 cup mango puree, add some milk, top with vanilla/mango ice cream or whipping cream, garnish with cherries and some more mango pieces. Enjoy this refreshing drink :)
