Sanatana Dharma literally translates to “nature law”, it is the authentic yoga. Karma Yoga is a practice of “meditation trough working”; to be active, doing any kind of work as an instrument of the divine, while remaining in the present moment without expectation for reward. Combined with Japa (repeating any mantra such as “Om Namah Shiva” while gently steering the mental power towards the divine) it becomes a work that goes with you even after death. Karma yoga is a very effective method towards preparation for the higher yoga, the last few beads of the eight fold path, or meditation, especially in Kali Yuga where the distractions of the material are strong.
