I myself continue to feel a positive benefit from K meditation, while having a full life generally post M involvement.

Just because Rawat talks in infuriatingly empty and vague sentences, we don't have to.  What do you think you're doing when you meditate on these techniques?  What kind of "benefit"?  You were originally told that they would connect you with God / your true self who was waiting to say hi just behind your mind.  That saying hi a lot would eventually let you merge with your new buddy.  That that would save you from something or other when you die. 

What do you believe now?
