This is purely based on personal experience.

TJ is a combination of Dawah to masses and a mobile Khanqah.

Offering dawah to common Muslims is an art and few TJ sathees posses that art. People like me do khurooj to spend time in deeni environment. As an alternative for this, can we have masajid, marakiz, islamic centres etc., where an environment is created similar to khurooj of TJ. Under the guidance of ulema, these ulema can be sponsored by the participants. The stay can range from 1 day to a month or more. The center must be open for 365 days in an year.

As I said, the daily schedule can have tahajjud and other nawafil, simple azkaar, tajweed halqas, taleem and muzakirah. A cook and few supporting staff can also be hired.

This reduces travel time, cooking, mujahidah of staying in tough environment etc.
