Here is another example of what white Dzambala is of benefit for.....
"Summoning Good Fortune,"
A short practice excerpted from the White Zhambala Sadhana.
This is the text for a traditional Tibetan ritual, where the practitioner calls upon White Zhambala to bestow his blessings--buddhahood, spiritual accomplishments, and all things positive in this life. H.E. Garchen Rinpoche asks his sangha to recite this text frequently, because it brings tremendous benefit to the whole world.
Here is a short exert from the prayer:
May I obtain the empowerment of mahamudra, which liberates from samsara's pain.
May I obtain the empowerment of self-knowing dharmakaya, which is primordially unsullied by the confused perceptions of unawareness. May I obtain the empowerment of the Great Completion, which is primordially unsullied by all phenomena of samsara and nirvana.
May I obtain the empowerment of the Great Middle Way, which naturally liberates the four extremes of permanence and annihilation. May I obtain the empowerment of the Perfection of Transcendent Knowledge, which is inexpressible through descriptions or conceptions.
May I obtain the empowerment of openness free from fixation, which naturally liberates dualistic propensities.
May I obtain the empowerment of immortal life, which is the unchanging expanse of awareness.
May I obtain the empowerment of awakening within one lifetime, which is the endless [accumulation of] merit.
I have this short practice in .pdf if any one is interested.
all the best
