These days I'm regular in my devotion, I don't offer my meal to god and partake of the prasada, though one is supposed to be doing it. I pray only at 3 PM and at that time, offer god a little milk or bananas or raisins. But my sister-in-law who lives in NJ, USA regularly offers her meal to the deities before consuming them - I asked her what she offers - as Sumit exclaims, it is a bit of a habit one must cultivate. Because one has to take bath, cook and then offer food to god in the morning all on time to do it everyday. My sister-in-law told me she offers cooked plain rice and a cup full of curd only. She does not offer the vegetable, etc. (I think this is because she makes them after she offers food to god). Although it will be a good habit to get used to cooking them without onions, garlic and offer everything to god and take the prasad... I want to do it, but my cooking takes place very conveniently at 11:00 AM or even later, that I have no mood to offer god the food at a much later time in the morning.
I chant "Naivedyam samarpayami, shodasopachaaram samarpayami" (I'm offering food to god, I'm offering 16-different forms of services to the lord, please accept) and offer the food to the deities on festival days.
You are doing well yourself!
Even a little bit counts, does it not? Maybe you and I can hopefully be more devoted and do more offerings in the future!
I still struggle every day to be a good devotee, but I know that developing my humility, tolerance, and respect are the better qualities that I strive for!
Not cooking onions and garlic is easy for me, but my boyfriend who I live with likes garlic very much, so I cook them in order to satisfy him. Otherwise, there are always sweets (I haven't made a blueberry pie in a good while) that I could offer and make! Before, I lived with a family for some time with Vaishnava teenagers and mother who didn't bother with offerings, so their altar room (yes, the separate room for Deity worship) was neglected. I did puja there for a while, but due to association, I've fallen out of that standard!
I generally just do a very simple puja, offering lamp and incense mainly when it comes to food offerings. Doing everything else, like achamana, etc. just becomes too much, lol.
In the Math that I used to belong to, we were to always offer food to Guru first. The following are the mantras I generally use for naivedya, or bhoga, along with their interpretation:
Prayer to Srila B.S. Govinda Dev-Goswami Maharaj
gurvvabhishta supurakam guru ganair ashisha-sambhu****am
chintyachintya-samasta-veda-nipunam shri-rupa-panthanugam
govindabhidham ujjvalam vara-tanum bhakty anvitam sundaram
vande vishva-gurun cha divya-bhagavat-premno hi bija pradam
I worship the holy lotus feet of he who perfectly fulfils the most cherished wish of his divine master; who is adorned resplendently with the blessings of his guru-varga; who is adapt in all Vedic conceptions, both conceivable and inconceivable; who is the faithful follower in the line of Sri Rupa; who is known as Srila Govinda Maharaj; whose beautiful divine figure revels in the mellows of divine love; who is the guru of the entire universe and the bestower of the seed of divine love for the Supreme Lord.
Prayer to Srila Bhakti Rakshak Sridhar Dev-Goswami Maharaj founder of SCS Math
devam divya-tanum suchanda vadanam-balarka-chelanchitam
sandrananda-puram sad-eka-varanam vairagya-vidyambudhim
shri-siddhanta-nidhim subhakti-lasitam sarasvatanam varam
vande tam shubhadam mad-eka-sharanam nyasishvaram shridharam
I fall at the feet of Srila Sridhar-Deva, who with charming expression sings his songs of sweet nectar. Dressed with fine garments like sun newly risen, he's the true saint the devotees have chosen. His detachment and knowledge are just like an ocean, the treasure-house of complete, perfect conclusion. Radiant in pastimes of loving devotion, the abode of pure ecstasy, bestower of good fortune; foremost true follower of Srila Bhaktisiddhanta, foremost great general of the whole renounced order; my lord and my master, my only shelter, I worship his feet, Srila Sridhar-Deva.
Prayer to Sri Chaitanya (Sri Sri Prema-dhama-deva-stotram, verse 70)
prema hema-deva dehi-dasaresha-manyatam
kshamyatam mahaparadha-rashiresha-ganyatam
rupa-kinkareshu ramananda-dasa-sambharam
prema-dhama-devam eva naumi gaura-sundaram
O my Golden Lord! (suvarna-varna-hemanga) O ocean of prema! Kindly grant me the wealth of Your divine love! Please give me some slight attention to this fallen soul and pardon his unlimited offenses. There are so many servants of Sri Rupa who are so dear to You. My only aspiration is that You count me as one of those servitors. O Gaurasundar, You are the sole protector and embodiment of good fortune for me, a servant of Sri Ramananda. I offer my obeisances to you, O Gauranga Sundar, my most beautiful Golden Lord, the divine form of Krishna prema.
