Achieving Spiritual Fulfillment Through Karma Yoga

The yoga path that involves striving to do all useful work unselfishly without a desire for reward is known as Karma Yoga. Karma Yoga is one of the several paths in Hinduism that leads towards spiritual fulfillment and is associated with acting in accordance with one's dharma (duty) without attachment to the results.

This path emphasizes the importance of doing one's duty and engaging in righteous action as a means to spiritual progress and the ultimate state of enlightenment, or moksha. In contrast to Karma Yoga, Bhakti Yoga is the path of devotion, Hatha Yoga is often associated with physical postures and breath control, and Jnana Yoga is the path of wisdom or knowledge.

Thus, in the context of the provided options, striving to perform unselfish work without the expectation of rewards corresponds to Karma Yoga. By practicing Karma Yoga, individuals can cultivate selflessness, detachment from the outcomes of their actions, and a deep sense of duty towards others.

Through selfless service and detachment from personal gain, practitioners of Karma Yoga can attain spiritual growth, inner peace, and ultimately realize their true nature. This path teaches individuals to focus on the process of action rather than the results, leading to a more fulfilling and purposeful life.
