Nityananda

“I’m saying that if you want to be happy, eradicate your attachment; cut your concrete concepts. The way to cut them is not troublesome—just change your attitude; switch your attitude, that’s all. It’s not really a big deal! It’s really skillful, reasonable. The way Buddhism explains this is reasonable. It’s not something in which you have to super-believe. I’m not saying you have to try to be a superwoman or superman. It’s reasonable and logical. Simply changing your attitude eliminates your concrete concepts.”
