I might strongly suggest following Mikao Usui’s recommendation. Each morning and each night, sit for a second in Gassho and repeat the ideas.
However please take your time. I generally cease all of the sudden midway by and suppose: You didn’t imply it! And begin once more: ‘Only for at this time, I can't be offended [then I pause for a moment and check whether I’m holding anger or feelings of resentment], I can't fear [pause again: Am I worrying? Have I transfered my worries over to Reiki?], I will likely be grateful [pause again to see what comes up], I'll do my work with diligence [where do I need to improve?] and I will likely be sort to others [anyone in particular today?].’
