We are blessed to be gifted with four great boons as mentioned in Shrimad Bhagwad Puran : 

1. The Human Form ; After many births into various forms of life do we get this human form. What we can achieve and conduct in this form is comparable to another life form.  This form is so important that even Gods have had to take support of this form to depict their deeds and to achieve things on this Earth Planet. 
2. Affluence; We are surrounded by air, water, food and if these were not with us, we wouldn’t have existed.
3. Senses ; We have eyes, ears, limbs, mind, touch, memory. These things make us superior to several life forms that may not have all of these and the capability to use them like us. The discriminatory power is part of human life alone.
4. Power to Worship ; It is in this human form that one has the tendency to worship and pray to the Lord and to do various rituals.
