Karma yoga 11.20 of the "Bhagavata Purana" states that there are only three means to spiritual liberation: "jnana yoga" (knowledge), "karma yoga" (action) and "bhakti yoga" (devotion). Those who are of philosophical bent, prefer the "knowledge path". Those who are inclined to productive application of arts, skills and knowledge, prefer the "karma path". Those who prefer emotional connection, prefer the "devotional path". These three paths overlap, with different relative emphasis. Discussions on Karma yoga are also found in chapter 33 of "Narada Purana". Later, new movements within Hinduism added raja yoga as the fourth spiritual path, but this is not universally accepted
Karma unjust act, can claim all his bad actions were a product of his karma: he is devoid of free will, he can not make a choice, he is an agent of karma, and he merely delivers necessary punishments his "wicked" victims deserved for their own karma in past lives. Are crimes and unjust actions due to free will, or because of forces of karma? (2) Does a person who suffers from the unnatural death of a loved one, or rape or any other unjust act, assume a moral agent is responsible, that the harm is gratuitous, and therefore seek justice?
