Relation Between Souls, Pinds, Rebirth & Attaining Moksha
In Indian religions and Indian philosophy, moksha (Sanskrit: मोक्ष mokṣa), also called vimoksha, vimukti and mukti, means emancipation, liberation or release. In the soteriological and eschatological sense, it connotes freedom from saṃsāra, the cycle of death and rebirth. In the epistemological and psychological sense, moksha connotes freedom, self-realization and self-knowledge.
According to Hindu traditions, moksha is a central concept and included as one of the four aspects and goals of human life; the other three goals are dharma (virtuous, proper, moral life), artha (material prosperity, income security, means of life), and kama (pleasure, sensuality, emotional fulfillment). Together, these four aims of life are called Puruṣārtha in Hinduism.
The concept of moksha is found in Jainism, Buddhism and Hinduism. In some schools of Indian religions, moksha is considered equivalent to and used interchangeably with other terms such as vimoksha, vimukti, kaivalya, apavarga, mukti, nihsreyasa andnirvana. However, terms such as moksha and nirvana differ and mean different states between various schools of Hinduism, Buddhism and Jainism. The term nirvana is more common in Buddhism, while moksha is more prevalent in Hinduism.
Moksha has been defined not merely as absence of suffering and release from bondage to saṃsāra, various schools of Hinduism also explain the concept as presence of the state of paripurna-brahmanubhava (oneness with Brahma, the One Supreme Self), a state of knowledge, peace and bliss.
Hindus strongly believe that spirits of the dead hover around without getting salvation till Pind Daan offering is made to them. With the offering made as a part of the process called 'shraddha,' (Shradh, Shraadh) Pitru Paksha (16-lunar day period as per Hindu calendar) is considered as an important occasion for providing salvation to deceased souls. Once it is performed, souls are satisfied and attain salvation (moksha). With these days falling generally in the month of September every year, the ritual is mainly based on making food offerings for the departed souls that allow souls of their ancestors to be freed from the cycle of birth and death.
