Individual wrote:It includes a lot of superstitious beliefs and seems foolishly concerned with devotion to and unification with a supreme divinity, but you could say the same of quite a few Mahayana Buddhist groups also.
That's a quite arrogant remark to make.
When they speak about unifying with a supreme deity like Brahma, do you think those yogis assume it to be a big guy with a beard in heaven?
For example, 'Brahma' in some contexts means 'purity' and in that sense unifying with the 'ultimate purity', whether you represent it symbolically with artwork and make offerings to it or not, would encourage the practitioner to rid themselves of desires and devote themselves to meditation.
You really don't know much, Individual. You should cease making such foolish remarks and actually sit down and do your research before uttering such offensive things.
