I wonder if there may be any standardized practice of meditation in research program mediation is a way of thinking directly related to the mind thru inner urge & divinity within which may very often help & guide us in the relation to the intuition & inspiration with the power of prayer & religion practices .

Generally meditation remains individually a guiding process for the person who are devoted to religion ,power of prayer & subsequently meditation

This is my personal opinion

There is no as such standardized protocol of meditation in research because there are N number of traditions in meditation practice. Hence, when it comes to research, the method followed in that tradition of meditation is taken as it is for the study. it seems to be quite logical also because the methods of meditation practice evolve with immense experience of the masters in that respective tradition. So, the preliminary objective is to observe and compare the psychological, behavioral, physiological and emotional changes occurring within the practitioner or an individual because of the practices.

Moreover it doesn't seem to be correct to decide (if at all in future) on some scientific protocol of meditation as it is more important to consider the experience of an individual/practitioner.

Pray as true Christians do can serve as preparation to a researcher or any other person or worker.

Research follows scientific methods, and thus standardized procedures are necessary for the accurate interpretation of data obtained. Meditation being an umbrella term, there is no standardized protocol used for research purpose. But specific meditation practices, if they are scientific, will have certain pre-determined properties that must be followed by all researchers to make the results comparable.

Let me give an example. Mindfulness meditation is one of the most widely used meditation technique used in psychological researches. There is no single standardized form of mindfulness, but there are several mindfulness-based interventions, developed for and standardized among specific populations. For instance, Mindfulness Based Stress Reduction (MBSR), Mindfulness Based Cognitive Therapy (MBCT), Mindfulness Based Cognitive Behavior Therapy (MCBT), Mindfulness Based Relapse Prevention (MBRP), Dialectical Behavior Therapy (DBT), Acceptance and Commitment Therapy (ACT), and Mindfulness-Oriented Recovery Enhancement and so on have separate and specific set of goals and applicable in a particular population alone. What is required for stress reduction among people with mood disorders will be totally different from relapse prevention after smoking cessation. And, the procedures must also be standardized to ensure good reliability and validity.

The above mentioned techniques will yield comparable results because they all utilizes mindfulness skills for reducing clinical symptoms and promoting healthy behaviors. Duration for each therapy is also similar - approximately eight week to ten weeks on average.
