Q:

Laravel Blade Template : combine string with variable from controller for @yield parameter

My statement
@section('description', 'mastram masti mein aag lage {{ $mast->basti }} mein')

results in 
 mastram masti mein aag lage &lt;?php echo e($mast-&gt;basti); ?&gt; mein

A:

You need to do the concatenation of the variable here.
So you should do this 
@section('description', 'mastram masti mein aag lage ' . $mast->basti . ' mein')

instead of 
@section('description', 'mastram masti mein aag lage {{ $mast->basti }} mein')
