Want to catch a bus to Lahli village near Rohtak

Going for Vipassana session. The centre in Lahli village near rohtak. Guys can anyone tell me where I can board a bus for rohtak easily from gurugram. I don't feel like going to ISBT Kashmiri gate. Don't suggest any apps. Need a bus route where the frequency is high I can catch bus tomorrow morning. Any advice suggestions are highly appreciated. Thanks.
