The term meditation refers to a broad variety of practices which range from techniques designed to promote relaxation , contacting spiritual guides, building internal energy (chi, ki, prana, etc.), receiving psychic visions, getting closer to a god, seeing past lives, taking astral journeys, and so forth, to more technical exercises targeted at developing compassion, love, patience, generosity, forgiveness and more far-reaching goals such as effortless sustained single-pointed concentration,[3] single-pointed analysis,[4] and an indestructible sense of well-being while engaging in any and all of life's activities. Thus, it is essential to be specific about the type of meditation practice under investigation.
Meditation as a mere relaxation technique becomes extremely problematic when one attends to the details of many practices. In contrast, we should think about the term Meditation as referring to several neighborhoods of New Age practices, shamanistic lucid dreaming and astral journeying, theistic-concentration meditations, clinging to god, contemplation, visualization, hypnotherapy, aromatherapy , chakra clearing, kundalini, breathing exercises, training of single-pointed attention, training in mindfulness, training in single-pointed analysis, vision questing, chi building exercises, and so on, developed for various ends.We use Biofeedback and neurofeedback to achieve the deepest state of meditation which found to be more effective than using psychotropic medications and sleep medications with numerous side effects.
In my doctoral thesis on stress management at the University of Toronto, we found that meditation is the most effective method to reduce and minimize stress.
Meditation may involve generating an emotional state for the purpose of analyzing that state - such as anger, hatred, or cultivating particular mental response to various phenomena, such as compassion. The term meditation can refer to the state itself, as well as to practices or techniques employed to cultivate the state. In brief, there are dozens of specific styles of meditation practice; the word meditation may carry different meanings in different contexts. Meditation has been practiced since antiquity as a component of numerous religious traditions and beliefs.
People who meditate regularly and laugh often have much higher beta endorphins which regulates several brain neurotransmitters like serotonin responsible for happiness and dopamine for controlling sleep, appetite and sexual function.
If you feel stressed or unable to achieve deep sleep, instead of rushing for medications, I strongly recommend meditation.
