Is the path an individual journey? When seeking or on the path, is the journey intended to be for the one on the path or can it be travelled by more than an individual i.e. is the path different for each being?
The Path is the same for all beings, although since all beings have different kamma due to past actions, all beings are on different stages of the Path.

So one being might need to practice certain path factors, e.g. Sila more than another being and vice versa. 

Regarding The Ten Perfections (Paramis) they are often compared to jars and when one practices a parami one fills the jar with a drop. So again, how full a jar is, is different from being to being. One being might have worked extensively on the Dana-parami, while lacking in the Aditthana-parami. 

 


  Is the path an individual journey?


The Path proclaimed by a fully englightened Buddha is always the same. A fully enlightened Buddha does not invent the Path. He discovers the Path by himself with no help from anyone else, then he proclaims it and teaches it to other beings. Its often described as discovering an ancient path (purānam añjasam), covered by a dense forest which leads to a bygone kingdom.

The Path is an individual journey. No one can walk the Path for us. We ourselves has to work. Only oneself can free oneself. Only oneself can issue liberation from the rounds of suffering by practicing the Dhamma.

One has to become ones own refuge. The Buddhas only show the way and guide us but we ourselves must walk the Path. Throughout the Buddha's 45 years of teaching-career he constantly emphazized the importance of practicing diligently, consistently and with great effort in order to win Nibbana.

If you are interested in further readings about the self-reliance-factor of the Path, then I recommend the following chapter in the book "What Buddhists Believe", by Ven. K. Sri Dhammananda.
