grep/awk and bring multiple lines forward
Hello all, I have a question regarding grep and pulling the result forward to the next carriage return or line space. Sorry if I have terminology incorrect. I have the following data set.

Line1
Line2
Line3

Line5
Line6
Line7

Line9
Line10
Line11

I would like to grep for a pattern and have it pull all data forward to the next space. So if my match is in line1. I would see:
Line1
Line2
Line3

I would also like to go Northbound with it. So if my match is in Line6, I would see:

Line5
Line6
Line7

I can do something similar using grep -A, however, the number of lines and where the line spaces could occur is totally variable. Will a command accomplish this without the need for a Perl script? Any assistance is greatly appreciate.

Code:
awk -v t=0 'NF{a=a RS $0} /Line6/ {t=1} !NF{if (t==1) {t=0;print a} {a=""}}' infile
