When entering the Buddhist path, it is not sufficient to be a person who only adopts the outer appearance of a person on the path. Cut all entanglements to desirable things and to this life’s affairs. When you enter the gate to Buddhist practice without having cut these ties, you will lack determination but not attachment to homeland, wealth, possessions, lovers, spouses, friends, relatives, and so forth. Your attitude of attachment becomes an underlying cause; the objects of your attachment, catalysts. When these meet, negative forces will create obstacles. You will once again become an ordinary worldly person and will turn away from creating positive karma.

-- His Holiness Dudjom Rinpoche
