Tulkus are highly realised beings that have control over their birth and that choose to take rebirth amongst us for our benefit. They are recognised trough careful tests and precise rituals and divinations. They come back life after life, in an unbroken lineage. This training entitles them to become perfect teachers of Dharma. To teach Dharma is the supreme generosity, since it leads us towards the perfect and ultimate happiness and freedom.
Generosity is the best investment against mental and material poverty.
To remain attached to things because of greediness, egoism and fear is the best method to become unhappy, needy and wretched.
