Even saints or God cannot offer blessings without any ground. As you will see, had it been possible to offer blessings at free will, there would have been no sufferings left on the earth. You may not agree but God himself helpless regarding this matter. He does not have any access to your mind.
Everyone is after seeking cure. To seek the cure one must apply the force at some different point. Sufferings are outcome of ill-framed desires and they need to be controlled at the point of origin – mind. In this process, you will need assistance from a divine saint. I have been going to the Ashram of Shri Kripaluji Maharajaji for about 25 years and I don’t have any hesitation in recommending anyone to approach him for spiritual guidance. Wish you best luck on your spiritual path.
