The biggest hurdle in attaining eternal bliss or divine love of God is ego. Ego does not allow humility to develop. And God is the brother of humble (DeenBandhu). Hence he cannot be brother of egoist. You may do whatever you like, you are hitting your head against wall, unless ego is shed.

Because of ego you try to get recognized as good person outwardly and not try to become good person from within.

Ego reduces your tolerance. Small insults, bad words make you mad out of rage. You can not get over any thing that goes against your wish. It gives rise to anger. Out of anger you can take wrong decisions. You are not ready to accept mistakes. This makes you prone to committing more sins. High pitch emotions towards worldly persons makes your attachments more strong. You further go away from God.

Therefore if you wish to advance in spiritual world you must cultivate politeness, endurance, tolerance and humility.

Gaurang Mahaprabhu says,'Trinadapi sunichen Tarorapi Sahishunam, Amaniya mandeya Kirtaniya sadaa hari"

Be more humble than the blade of Grass. If someone tramples grass, it bows down and again come up slowly.

Be more tolerant than a tree. If someone hits the tree with stone, the tree returns its fruits. Fruit is the reply of tree for getting hit by stone! Trees don't own fruits themselves. They give it to others.

Do not desire own respect from others but offer respect to others and keep on chanting name of Krishn. So said Gaurang Mahaprabhu who was Krishn incarnate!
