It is based on the Vedant philosophy of "Ekmevadwitiyam Brahm" (the ultimate truth is one & only one Brahm) and "Sarvam Khalu Idam Brahm" (whatever is there, is Brahm). Ved, Brahma-sutras, Bhagwad Geeta and Shrimad Bhagawat are the four fundamental scriptures. The ultimate reality to which Ved & Brahmsutras refer as Brahm, Geeta refers as Parmatma and Shrimad Bhagawat refers as Bhagawan are all essentially one. This philosophy is called as "Sakar Brahmvad" or "Shuddhadwait Brahmvad", which is the fundamental doctrine of Mahaprabhu Shri Vallabhacharya. The path to be followed to attain the ultimate blissfulness based on this principle is called as Pushtimarg. The same Bhagawan is to be lovingly serviced in the form of Deity as Shri Krishna who is "Sachchidanand Purushottam Parambrahm". It (Pushtimarg) is spontaneous, selfless and motiveless love for Shri Krishna. It is based on pure love for Shri Krishna. It is expressed only through selfless service of Shri Krishna - "Seva". It is love after realising Shri Krishna's true nature. The knowledge gained is not a means of liberation. Liberation is considered secondary to the enjoyment of Shri Krishna's bliss. Its aim is Shri Krishna's happiness. No caste, creed, color, sex or age prevents one from attaining Shri Krishna's Grace. It does not know any boundaries, be it time, place, or anything else. It does not require a devotee to give up a householder's life. In fact, one can serve Him better by being a householder. This is different from other philosophies that require a life of contemplation as a monk. All worldly desires are diverted towards Shri Krishna; they are then not required to be suppressed. The world is not looked down upon but is treated as Shri Krishna's creation, and thus as real as Shri Krishna himself. Shri Krishna is the Supreme Deity; all the other deities reside in his form. Therefore, total faith is placed in Shri Krishna alone. In the state of liberation, the entity of the devotee merges into *Shri Krishna's blissful form. However, in Bhakti (especially Pushti bhakti), the devotee does not seek liberation: he enjoys Shri Krishna's bliss by participating in it as a separate divine entity.
