Many other puja components that are considered auspicious (sattvik) as per Vedas are used to worship deities and to perform various Vedic rituals. Hinduism is referred as Dharma (a way of living) which guides the followers just not to achieve external happiness but internal blissfulness to live and experience life in the fullest possible way.
Shivaratri Pooja has its importance in Hindu culture. It is believed that if you worship Lord Shiva on this auspicious day of Mahashivratri, Lord Shankara blesses you with a healthy and happy life. It also helps you eliminate the sins of the past and gives you salvation.
