As per Hindu Dharma when an individual leaves for the heavenly abode, his blood relations are supposed to do his yearly /annual ritual. It is deemed that the departed soul gets its feed  on the thithi or the day every year.

The standard way to do the same is to do a ritualistic fire and a process of feeding called Shradham

Due to various circumstances the concerned blood relation of the departed soul is hard pressed  for time in his worldly duties that he is forced to do a simple ritual the same is called Hiranya shradham

Under Hiranya shradham food materials and Dakshanai is offered to the priest who conducts  the ceremony.

श्राद्धंकन्यागतेभानौयोनकुर्याद्गृहाश्रमी।
धनंपुत्राःकुततस्यपितृकोपाग्निपीडनात्।।
यावच्चकन्यातुलयोःक्रमादास्तेदिवाकरः।
शून्यंप्रेतपुरंतावद्यावद्वृश्चिकदर्शनम्

It is important not to miss out on such deeds of remembering ones departed family members every year as  appeasing them  helps in getting blessing for the prosperity of the family
