In Siddha Yoga, seva or selfless service is considered an essential aspect of the spiritual path. It is seen as a way to purify the mind and cultivate selflessness, compassion, and detachment. Swami Muktananda, the guru of Siddha Yoga, emphasized the importance of seva in his teachings and encouraged his students to engage in it regularly.

One of the main reasons for the emphasis on seva in Siddha Yoga is the belief that true spiritual growth can only happen when one's mind is free from selfish desires and attachments. Through seva, one learns to let go of personal desires and focus on the needs of others. This helps to develop a sense of detachment and selflessness, which are essential qualities for spiritual evolution.

Moreover, seva is seen as a means to purify the mind and cultivate positive qualities such as humility, gratitude, and compassion. By serving others, one learns to see the divine in everyone and everything. This helps to break down the barriers of ego and cultivate a sense of oneness with all beings. Swami Muktananda often said, "When you serve others, you are serving God."

In Siddha Yoga, seva is not limited to traditional acts of service such as volunteering or donating money. It is seen as a way of life, where every action is done with a sense of selflessness and devotion. This includes everyday tasks such as cooking, cleaning, and taking care of others. Swami Muktananda believed that even the simplest act, when done with the intention of serving others, can have a profound spiritual impact.

Furthermore, seva is seen as a way to express gratitude towards the guru and the divine. In Siddha Yoga, the guru is seen as the embodiment of the divine and serving the guru is seen as a way to honor and show gratitude for the blessings received. Swami Muktananda often said, "Seva is the highest form of worship."

In conclusion, seva plays a vital role in Siddha Yoga as it helps to purify the mind, cultivate positive qualities, and deepen one's spiritual practice. Through selfless service, one learns to let go of selfish desires and attachments, and instead focus on the needs of others. Swami Muktananda believed that seva is not just an act of service but a way of life, and through it, one can experience the true essence of the spiritual path.
