Spiritual Benefits
“It is the practice of Vaiṣṇavas while taking prasādam to chant the holy name of Lord Hari at intervals and also sing various songs, such as śarīra avidyā-jāla. Those who are honoring prasādam, accepting the remnants of food offered to the Deity, must always remember that prasādam is not ordinary food. Prasādam is transcendental……. One should take prasādam with great faith and should chant the holy name of the Lord and worship the Deity in the temple, always remembering that the Deity, mahā-prasādam and the holy name do not belong to the mundane platform. By worshiping the Deity, eating prasādam and chanting the Hare Kṛṣṇa mahā-mantra, one can always remain on the spiritual platform (brahma-bhūyāya kalpate).” ~ CC Madhya 11.209
“Mahā-prasādam is nondifferent from Kṛṣṇa. Therefore, instead of eating mahā-prasādam, one should honor it. It is said here, karilā vandana, "he offered prayers." When taking mahā-prasādam, one should not consider the food ordinary preparations. Prasāda means favor. One should consider mahā-prasādam a favor of Kṛṣṇa. As stated by Śrīla Bhaktivinoda Ṭhākura, kṛṣṇa baḍa dayāmaya karibāre jihvā jaya svaprasāda-anna dilā bhāi. Kṛṣṇa is very kind. In this material world we are all very much attached to tasting various types of food. Therefore, Kṛṣṇa eats many nice varieties of food and offers the food back to the devotees, so that not only are one's demands for various tastes satisfied, but by eating prasādam one makes advancement in spiritual life. Therefore, we should never consider ordinary food on an equal level with mahā-prasādam.” ~ CC Antya 11.20
“Because prasāda is transcendental. It is not material thing. So one must have faith that it is not material. It cannot be infected by any material things. In this way prasāda should be taken. It is called prasāda-sevā, not "prasāda enjoyment." Sevā means giving service. Prasāda is as good as Kṛṣṇa; therefore prasāda should be respected as good as Kṛṣṇa. As soon as one gets prasādam, immediately he touches on the head because it is Kṛṣṇa, absolute.”
