We are beset by problems and if we look for their source, we find they arise because of our selfishness, because we tend to pursue our own interests at the expense of others. Our various religious traditions exist to help us reduce these problems. They all teach ways to overcome suffering through cultivating love and compassion, tolerance, patience and contentment.
If one's cause is supported by sound reasoning, there is no point in using violence. It is those who have no motive other than selfish desire and who cannot achieve their goal through logical reasoning who rely on force.

Too much of a self-centered attitude creates mistrust and suspicion in others, which can in turn lead to fear. But if you have more of an open mind, and you cultivate a sense of concern for others' well-being, then, no matter what others' attitudes are, you can keep your inner peace.

It is also possible within this lifetime to enhance the power of the mind, enabling one to reaccess memories from previous lives. Such recollection tends to be more accessible during meditative experiences in the dream state. Once one has accessed memories of previous lives in the dream state, one gradually recalls them in the waking state.
When we are young and again when we are old, we depend heavily on the affection of others. Between these stages we usually feel that we can do everything without help from others and that other people's affection is simply not important. But at this stage I think it is very important to keep deep human affection.
