Lets treat the first meaning as we often hear people say I want it too to mean I too want it. This becomes a statement that indicates reason for wanting. The problem with one wanting realization because someone 'else' (pun intended) wants it is that one may not be necessarily ready. There is a right reason for wanting to liberate oneself and that right reason is viveka-driven vairAgya. No other reason is apt, nor is the sAdhana fruitful with such foundation. Enough said on this point.
The issue with wanting realization among other things in life is that of lack in mumukshutva. This is a major hurdle on the path... why, sAdhana cAtuShTaya must culminate in mumukshutva to become an utammottama adhikAri of j~nAna. The burning desire to liberate means the only desire, which itself becomes a cause in getting the Guru. The Guru is said to search and find such a mumukshu himself! Since that is an extreme rarity in an already rare number of seekers, the remaining grades of uttama, madhyama and manda adhikAris in decreasing order of mumukshutva must achieve citta shuddhi by focusing entirely on sAdhana cAtuShTaya. Such grades of adhikAris also benefit due to physical proximity to the Guru, which again means wanting only one thing in life. Ones who neither have the intensity in desire to liberate, nor focus entirely on achieving purity of mind are the ones who want realization also among other things. Unfortunately, most of us are not even a part of manda adhikAris, but are of pastime philosophical needs in our cozy lives. Such people go nowhere on the path because its more of an arm-chair philosophy for them, something to chat about over a cup of coffee. And here's why...
When we want other things, the basic step of viveka itself is not going well. We are unable to discriminate between the real and unreal, end up living almost the entire day in the unreal, believing it to be real and trying to gain most of it towards the unreal goals. Take an example of a person who wants to make more money. He would go out of his way to spend more time at work to the expense of his family. Would this person do the same towards his goal to liberate and at the cost of the family? No! Our social norms declare the earlier kind as a hardworking person, while the latter is supposed to be an irresponsible chap, regardless of whether the society understands anything at all between the real and unreal. Therefore, vairAgya is difficult to come by for such people who try to be seekers. Without these basic qualifications, Bhagavatpada says in Vivekachudamani that even the practice of shaTsampatti is as useless as a mirage in the desert. How then will such a person gain mumukshutva, let alone liberation? Bhagavatpadacharya says in Kathabhashyam: न हि बाह्यविषयालोचनपरत्वम् प्रत्यगात्मेक्षणं च एकस्य सम्भवति। It is not possible for one and the same person to have commitment to dwelling on external objects and appreciation of the inner self!
In closing I'll quote a little-known teacher, Dr. Poy, who had once convincingly told someone so--
You asked for my teachings and here they are: ''Part-time sadhus don't get enlightened.''
