Dharma, Artha, Kama and Moksha are the purposes of life defined in Hinduism. The Moksha is ultimate destination of life. Various Hindu scriptures, especially Shrimad Bhagavad Gita enlightened the four paths of Moksha or self-realisation or enlightenment viz. the path of wisdom (Jnana yoga), the path of devotion (Bhakti yoga), the path of action (Karma yoga), and the path of meditation (Raja yoga).
The prevalence of the different paths has been in four yugas. In Satya-yuga, the path of meditation and Yagas, in Treta-yuga, the path of worship by the rituals and asceticism, in Dvapara-yuga, by following the path of ritual worship as per prescriptions of both the Vedas and tantras and in the Kali-yuga, the paths of Jnana and the Bhakti are predominant.
Medieval India saw upsurge of Bhakti movement. Saint Tulsidas (born in Kashi now called as Varanasi, UP, year- 1478-1624 AD), one of proponent of bhakti movement, authored Ram-Charitr-Manas in seven chapters, detailing about life of Maryada Purushottam Bhagwan Shri Rama. In fifth chapter named as Sunder Kanda, he vividly explained about crossing of Indian Ocean by Shri Hanuman, entering into Lanka in search of Ma Sita, the meetings with Sursa, Demoness, Lankani, Vibhishan, Ma Sita, Meghnath & Ravana in Lanka, return to Kishkindha and other accounts about movement of army of Shri Rama near Ocean to cross it.
Sunder-Kanda means “beautiful-Chapter”. Sunder- Kanda is so called because it gives a detailed account of a devotee's journey on the path of a virtuous life and spiritual transformation. Shri Hanuman, the devotee is inspired by ‘Jamvant’, who symbolizes intelligence; motivates Hanuman to move ahead in spiritual journey. Sense control is the bridge through which one can cross the ocean of mundane attachments. If a seeker lives with discipline, he will not drown in the ocean of mundane attachments. On the way of spiritual journey, many people and situations create obstacles in the spiritual progress.
Both, the paths of Jnana and Bhakti are revealed in the Chanting of Sunder Kanda.
The Sunder-Kanda helps human beings in Kalyug to overcome problems. It has been sung by Tulsidas & anyone who says it, can go through life without pain & difficulty, as Shri Ram is an Ocean of Peace & happiness. (यह चरित कलि मल हर जथामति दास तुलसी गायऊ॥ सुख भवन संसय समन दवन बिषाद रघुपति गुन गना। तजि सकल आस भरोस गावहि सुनहि संतत सठ मना॥ 5/60)
