Do not take bayah with another master because this is not the correct manner of taking the path. You can take bayah barakah but you need permission from your spiritual master to do this. Do not do this without permission. In some instances you may need to take bayah tarbiyyah with another Sheikh when ones own is no longer available for one to access or dies or there is a problem that means one cannot access the teachings.
The spiritual way is not something to be trifled with and nor is it an easy matter.
