Spiritual literature can be a great aid to

Spiritual literature can be a great aid to an aspirant, or it can be a terrible hindrance. If it is used to inspire practice, motivate compassion, ad nourish devotion, it serves a very valuable purpose. If scriptural study is used for mere intellectual understanding, for pride of accomplishment, or as a substitute for actual practice, then one is taking in too much mental food, which is sure to result in intellectual indigestion.

It?s important that what thoughts you are feeding

It?s important that what thoughts you are feeding into your mind because your thoughts create your belief and experiences. You have positive thoughts and you have negative ones too. Nurture your mind with positive thoughts: kindness, empathy, compassion, peace, love, joy, humility, generosity, etc. The more you feed your mind with positive thoughts, the more you can attract great things into your life.

We habitually erect a barrier called blame that

We habitually erect a barrier called blame that keeps us from communicating genuinely with others, and we fortify it with our concepts of who’s right and who’s wrong. We do that with the people who are closest to us and we do it with political systems, with all kinds of things that we don’t like about our associates or our society.

It is a very common, ancient, well-perfected device for trying to feel better. Blame others….Blaming is a way to protect your heart, trying to protect what is soft and open and tender in yourself. Rather than own that pain, we scramble to find some comfortable ground.
