@KhyungMar The Lama Yeshe book that I have been spending a great deal of time with is “The Bliss Of Inner Fire, Heart Practice of the Six Yogas of Naropa”. This is an excellent guide to the teachings of Je Tsongkhapa in his manuscript that is commonly referred to as “The Three Inspirations”. I spend a great deal of time in that book as well to get the direct verbiage of the teachings.
Lama Yeshe’s book, though, is an excellent and very detailed introduction to the Yoga of Inner Fire (Tummo). I do practice his version of Tummo regularly (each morning) and sometimes during the night as well during WBTB periods, even though the teachings indicate that Tummo is best practiced during the day.
Tsongkhapa states that if one is able to gather the vital energies into the central channel during the waking state and then dissolve them into emptiness then no other method is needed to retain dreams at night. During this period in my training I am working with that and having good success.
I agree with you about Tsa Lung Trulkhor. It is amazing to feel each chakra open up. Trulkhor right into Tummo is a very strong combination.
Regarding chakras, my protocols are greatly dependent on how I feel each night. Generally I meditate on the throat chakra when falling asleep after setting a strong intention for the night and then I work with the forehead in the first waking (usually two hours or so). This keeps me close to sleep but keeps the sleep light. Often times I will stay with the forehead chakra on the third waking without letting myself wake fully. The real conscious dream awareness for me comes late in the night from meditating on the heart chakra and the Vajra body.
Last night my early meditations were somewhat casual and after five hours of good sleep I stayed up for an hour and practiced both Tsa Lung Trulkhor and Tummo. Upon returning to bed I meditated strongly on the heart chakra (21 breaths) and then did a bit of classic SSILD while concentrating on feeling my Illusory Body. My dreams after that were strong and lucid and I awoke feeling incredibly light and refreshed.
