Sri Ramanuja Munaye Namaha,
Sri Velukkudi Krishna Swami Guruve Namaha,
Swami’s says in enpani 96 “Prasadham for SriKrishnan Jayanti”., in a detailed way. Offering the “NeiVedhyam” (cooked food using Satvik ingredients, fruits, water etc..) and put Thulsi leaves before offering to SriKishna and we get in return as “Prasadham (Ucchistam)” of SriKrishna.
Swami also says, depending up on our Yatha Shakthi, offer what we could to SriKrishna.
So, when Tulsi leaves are available, put one leaf on each Neivedhyam before offering to SriKrishna.
If BhagavAta is living outside India, then during winter times, it is tough to have Tulsi plant. Adiyen has heard that some people keep it in a pot inside their home, but still the plant doesn’t survive through the winter as it is freezing cold for 4~5 months. In those cases, just do Manasikam offering of Tulsi leaves to the food, water etc…before offering to SriKrishna.
Just say any Namaas of Bhagavan SriKrishna in mind everytime or Say these three Namaas everytime, before drinking water or before having prasdham.
Achudhaya Namaha (Purifies our Body)
Ananthaya Namaha (Purifies our Mind)
Govindaya Namaha (Purifies our Athma)
Swami says in the enpani, “Ullam Anbodaey kuduppadhai dhaan SriKrishnar yedhirpaarkkiraar“. “Yaar kuduthaalum yettru kolvaaar”, “Yeadhum illadhavargal mudiindhadhai kuduthaal, adhaiyum yettru kolvaar”, Ullatthil Thooymai irundhal yetrru kolvaar”.
So, don’t worry much.
Adiyen Sri Velukkudi Krishna Dasan,
Uyya Oraey Vazhi UdayavAr ThiruvAdi,
