Buddha was speaking about reality. Reality may be one, in its deepest essence, but Buddha also stated that all propositions about reality are only contingent. Reality is devoid of any intrinsic identity that can be captured by any one single proposition - that is what Buddha meant by "voidness." Therefore, Buddhism strongly discourages blind faith and fanaticism.

Peace isn't the mere absence of violence; peace must come from inner peace. And inner peace comes from taking others’ interests into account.

If you become more concerned for the welfare of others, you will experience a sense of calm, inner-strength, and self confidence.

Not only can I not recall my experiences in my previous lives, sometimes I can't even remember what I did yesterday.

As far as ignorance is concerned, not just Buddhism, every religion recognizes it as the source of suffering.

To the extent that our experience of suffering reminds us of what everyone else also endures, it serves as a powerful inspiration to practice compassion and avoid causing others pain. And to the extent that suffering awakens our empathy and causes us to connect with others, it serves as the basis of compassion and love.

Meditation is valuable for all of humanity because it involves looking inward. People don't have to be religious to look inside themselves more carefully. It is constructive and worthwhile to analyze our emotions, including compassion and our sense of caring, so that we can become more calm and happy.
