I am following tutorial to play Om Jai Jagdish Hare.
The gentleman says we can use Meend in Bansuri. He explains it is a soft way to go from one note to the next.
How would I do it.
The video starts playing at 2:39
As he demonstrates in the video 'meend' is the slight slide or glissando between notes you can get by placing the finger on the hole slowly or removing it slowly. This is typical of the Indian playing style.
It's a specific, more extreme, form of 'legato' which is a general term referring to any kind of soft transition from one note to another.
I don't know the term 'Meend' but I'm pretty sure 'legato' is what you're looking for.
Legato just means to transition smoothly between two notes, so that you basically fade from one note into another one.
I just answered a similar question a couple weeks ago. You may look into this thread, since I think this answers your question as well: How to transition between notes in Bansuri
