The very requisite commandment at the initial level to join Buddhism is to adopt Bhikshu Dharm to practice it where the aspirant takes a pledge to be a Bhikshu for his sustenance solely depending on Bhiksha (alms) going door to door for the purpose. The other rituals follow thereafter. Lord Buddha himself underwent through the process.The followers of Mahabir Swami too follow this ofcourse with different modus operandi in different places.The major difference is that in Buddhism alms process is initiated by the follower concerned himself whereas in Mahabir Swami’s creed the bhaktas (devotees) organise a dinner inviting some Guru (preacher) to taste it and whomsoever is extended this favour he is granted membership to join the clan as a Bhikshu –the number could be anywhere from zero to 100 at a time or even more. Whichever food is okayed by the Guru is admitted into the fold as a Bhikshu. The practice is prospering well in both the clans for thousands of the years. The world has changed a lot and so are the religions but the question is whether or not this would continue further sticking to dogmas like this.Wish the pursuers all the best.
