Answer in Details
According to Shiva Purana and various Shaiva texts, offerings and donations should be made with a pure heart, humility, and compassion. When giving food or anything else, do so with love and respect, seeing the divine in all beings. Lord Shiva teaches us to conquer anger and practice detachment (vairagya), compassion (karuna), and self-control.
Donating food with anger is discouraged, as it carries negative vibrations and does not bring true merit (punya). Instead, strive to cultivate a calm and generous mind, and offer food as a form of worship to Lord Shiva, who is present in all living beings. This aligns your actions with Shiva’s teachings and invites his blessings.
