Inner peace (or peace of mind) refers to a state of being mentally and spiritually at peace, with enough knowledge and understanding to keep oneself strong in the face of discord or stress. Being "at peace" is considered by many to be healthy (homeostasis) and the opposite of being stressed or anxious. Peace of mind is generally associated with bliss and happiness.
Peace of mind, serenity, and calmness are descriptions of a disposition free from the effects of stress. In some cultures, inner peace is considered a state of consciousness or enlightenment that may be cultivated by various forms of training, such as prayer, meditation, T'ai Chi Ch'uan or yoga, for example. Many spiritual practices refer to this peace as an experience of knowing oneself. Finding inner peace is often associated with traditions such as Buddhism and Hinduism.
Tenzin Gyatso, the 14th Dalai Lama, emphasizes the importance of inner peace in the world:
The question of real, lasting world peace concerns human beings, so basic human feelings are also at its roots. Through inner peace, genuine world peace can be achieved. In this the importance of individual responsibility is quite clear; an atmosphere of peace must first be created within ourselves, then gradually expanded to include our families, our communities, and ultimately the whole planet.[1]The meaning of life constitutes a philosophical question concerning the purpose and significance of human existence or biological life in general. This concept can be expressed through a variety of related questions, such as Why are we here?, What's life all about? and What is the meaning of it all? It has been the subject of much philosophical, scientific, and theological speculation throughout history. There have been a large number of answers to these questions from many different cultural and ideological backgrounds.
The meaning of life is deeply mixed with the philosophical and religious conceptions of existence, consciousness, and happiness, and touches on many other issues, such as symbolic meaning, ontology, value, purpose, ethics, good and evil, free will, conceptions of God, the existence of God, the soul, and the afterlife. Scientific contributions are more indirect; by describing the empirical facts about the universe, science provides some context and sets parameters for conversations on related topics. An alternative, human-centric, and not a cosmic/religious approach is the question "What is the meaning of my life?" The value of the question pertaining to the purpose of life may be considered to be coincidal with the achievement of ultimate reality, if that is believed by one to exist.
