Grandmapele,
There are very brief reference to various types of offering in the short sadhana, slightly more elaborate in the medium length, and very descriptive extensive offerings in the Kangso. There is another thread topic under this General Discussion link, I believe titled Commitment Fulfilling Relying and Appropriate Substances. I mention some details there which are very beautiful and taken from Je Kelsang Gyatso Rinpoche's Heart Jewel and an oral commentary he gave on the subject. It is typical to have outer offerings, serkyem, the 5 auspicious substances of alcohol tea cakes milk and curd, and either condensed tormas or elaborate tormas for Kangso. However, not only is it important to personalize (which is why I mention the other thread topic) but when you read of all the offerings in kangso, it really opens up the possibility to acquire many other items if one wishes. I do firmly believe though that we ought to take great care before placing wrathful offerings on our shrine in particular.
Lotus1,
Thank you for the beautiful pictures. While the outer offerings such as you depict are included in the fulfilling substances, I am referring to the section of Kangso where many peaceful and wrathful offerings are elaborately exclaimed. After confession, we bless the fulfilling substances, bless a special torma, then perform the actual offerings. I am about to move and most of my stuff is boxed up, but when I get settled I will post here pictures of the fulfilling substances for Yakya Chamsing and Palden Lhamo. You know, they are quite similar with only minor differences, and it isn't that imagining the offerings is difficult, I first asked simply wondering if anybody had a picture. The pictures I have are actually drawings/paintings. In actual Protector gompas, traditionally and to this day in some, there are quite wrathful substances actually placed on the shrine…I will not say what because I'm not sure if such things have ever been published or mentioned publicly, but if you let your imagination run a bit wild you'll probably be close or spot on.
