Persons with positive thoughts and grateful minds create a happy disposition which further contributes to creating an emotionally and mentally healthy society. This study aims to establish the philosophy of the Law of Attraction which harnesses positive thinking and gratitude towards happiness and determine the level of gratitude and happiness of the experimental and control groups before and after the introduction of the Law of Attraction’s 28 practical steps. This research is qualitative-quantitative quasi-experimental. There were two groups in this study – the experimental group and control group with 34 participants each. The experimental group underwent the 29-day lecture-training about the Law of Attraction’s 28 practices. Findings revealed that during the pretest, the experimental group had a lower level of gratitude and happiness compared with the control group. During the three posttests, the experimental group consistently manifested a robustly higher level of gratitude and happiness compared with the control group. The significantly high level of happiness of the experimental group in three posttests may be attributed to its high level of gratitude. The high level of gratitude of the experimental group may be attributed to the lecture-training on the Law of Attraction’s 28 practices to harness positive thinking and gratitude towards happiness.
