Dharma represents a structured religion or religious practice that is mandatory in the scriptures of recognized Monotheistic religions such as Christianity, Buddhism, Islam, and Judaism. The term Dharma goes back to early Sanskrit. Sanskrit Dridhatoo means to sustain or hold on to something that is related.
