1. Srimad Bhagavatam Canto 1 Chapter 4 Text 24-27
Vedas made easy for less intelligent class of men

2. Text 24
ta eva vedā durmedhair dhāryante puruṣair yathā evaṁ cakāra bhagavān vyāsaḥ kṛpaṇa-vatsalaḥ Thus the great sage Vyāsadeva, who is very kind to the ignorant masses, edited the Vedas so they might be assimilated by less intellectual men.

3. WHY DIVIDE THE VEDA?
The seed of all knowledge, or the Veda, is not a subject matter which can easily be understood by any ordinary man.
There is a stricture that no one should try to learn the Vedas who is not a qualified brāhmaṇa, and this stricture has been wrongly interpreted in so many ways.
The Vedas are subjects which had to be explained even to Brahmājī by the Supreme Lord.
Therefore the subject matter is understood by persons with exceptional qualities of goodness.
The ultimate goal of Vedic knowledge is Śrī Kṛṣṇa, the Personality of Godhead. This Personality is very rarely understood by those who are in the modes of passion and ignorance.
The kindhearted, powerful sage Śrīla Vyāsadeva divided the Vedas in various ways so that they may be practically followed by less intelligent persons in the modes of passion and ignorance.

4. Text 25 strī-śūdra-dvijabandhūnāṁ trayī na śruti-gocarā
karma-śreyasi mūḍhānāṁ
śreya evaṁ bhaved iha
iti bhāratam ākhyānaṁ
kṛpayā muninā kṛtam
Out of compassion, the great sage thought it wise that this would enable men to achieve the ultimate goal of life. Thus he compiled the great historical narration called the Mahābhārata for women, laborers and friends of the twice-born.

5. IMPORTANCE OF SAMSKARAS
The friends of the twice-born families are those who are born in the families of brāhmaṇas, kṣatriyas and vaiśyas, or the spiritually cultured families, but who themselves are not equal to their forefathers.
Twice-born - One birth is calculated during the seed-giving saṁskāra, and the second birth is calculated at the time of spiritual initiation.
The seed-giving reformatory process is called garbhādhāna-saṁskāra.
If the father and the mother do not undertake the process of spiritual family planning and simply beget children out of passion only, their children are called dvija-bandhus.
These dvija-bandhus are certainly not as intelligent as the children of the regular twice-born families.
The dvija-bandhus are classified with the śūdras and the woman class, who are by nature less intelligent.
The śūdras and the woman class do not have to undergo any saṁskāra except the ceremony of marriage.

6. Bhagavad Gita – The summary of Veda
Mahābhārata was prepared for the less intelligent classes of men, namely women, śūdras and unqualified sons of the higher castes.
The purpose of the Mahābhārata is to administer the purpose of the Vedas, and therefore within this Mahābhārata the summary of Veda, Bhagavad-gītā is placed.
The less intelligent are more interested in stories than in philosophy, and therefore the philosophy of the Vedas in the form of the Bhagavad-gītā, is spoken by the Lord Śrī Kṛṣṇa.
The Bhagavad-gītā is the essence of all Vedic knowledge. It is the first book of spiritual values, as the Upaniṣads are.

7. Text 26 evaṁ pravṛttasya sadā bhūtānāṁ śreyasi dvijāḥ
sarvātmakenāpi yadā
nātuṣyad dhṛdayaṁ tataḥ
O twice-born brāhmaṇas, still his mind was not satisfied, although he engaged himself in working for the total welfare of all people.

8. Text 27 nātiprasīdad-dhṛdayaḥ sarasvatyās taṭe śucau
vitarkayan vivikta-stha
idaṁ covāca dharma-vit
Thus the sage, being dissatisfied at heart, at once began to reflect, because he knew the essence of religion, and he said within himself:
