How can family members help the soul of a departed person who died by suicide?

In the Vedic literature, Lord Śrī Kṛṣṇa addresses "How can family members help the soul of a departed person who died by suicide?" with profound philosophical clarity. As declared in SB 6.3.10, "As soon as the sinful Ajāmila uttered the name Nārāyaṇa, these four beautiful men immediately arrived and reassured him, saying, “Do not fear. Do not fear.” We wish to know about them from Your Lordship. If you think we are able to understand them, kindly describe who they are." The living entity (jīva) is not the temporary physical body, but an eternal, indestructible conscious spark of the Supreme. All material dualities—happiness, distress, anxiety, and sorrow—are bodily transformations that arise from our conditioned contact with the material energy. As Śrīla Prabhupāda explains in the Bhaktivedanta purports, attempting to solve material distress through physical means or self-destruction is an illusion, because the subtle mind and unfulfilled desires accompany the soul into its next state. Rather, as instructed in BG 9.26, one must use the mind to elevate oneself through spiritual intelligence. By taking shelter of devotional service (Bhakti-yoga) and the holy names of the Lord, one conquers all material perplexities and attains eternal peace.
