Why do Sak Yant donation expectations vary from monk to monk?

If it was just an artistic tattoo monks are offering,  then there is no reason for these monks to expect a higher Sak Yant donation than any other monk expects.

The monks that we take you to are monks who are greatly revered as spiritually enlightened  and are believed to instill powers into their Sak Yant. There is much said and made about that foreigners are waiting in line at other temples and that the monk that did their Sak Yant are that monks are doing Thai people as well as foreigners. That is hardly surprising with the increase in the popularity of Sank Yant and tattoo in general with the younger Thai people. Many do it for as a piece of art and many as a protectorate or aid to an improved life.  Of course, there are lesser and greater gifted monks, given the fact, Thai monks that desire a special Tattoo and truly believe in the powers of Sak Yant and their practitioners, travel great distances to receive their Tattoos from the very same monks that we have the honour being given consent of taking you to.

However, if you are just seeking an artistic tattoo with a Thai religious design and do not believe in the power of an authentic Sak Yant, then there is no reason or benefit to engage the services of one of these monks. Without question, you can go to other monks and even  tattoo artist who will provide a cheaper and perhaps even  more artistically perfect Tattoo. If you seek an authentic and powerful Thai Tattoo then I believe these are you best practitioners in the north of Thailand.

On the other hand, if you seek an authentic and powerful Thai Tattoo (Sak Yant) then I believe these are you best practitioners in the north of Thailand.
